We make podiums for the VAZ 2114: how to do it right

The word “Podium” came to us from England and means elevation, convexity. An acoustic podium in a car is a special convex structure for mounting a speaker of any size. Owners of the domestic automobile industry prefer podiums to be able to install musical equipment of any segment and enjoy high-quality sound on the road.

VAZ 2114 podiums

Tools and materials

First of all, you will need to stock up on materials and tools with which you can make a shelf. This list includes:

• Sheet of plywood - 2 pieces with a thickness of at least 5 millimeters;
• Cardboard sheet;
• Set of self-tapping screws;
• 2-3 furniture curtains;
• Electric jigsaw;
• Sandpaper;
• Marker;
• Shelf covering material;
• Roulette, ruler, etc.;
• Glue.

The design involves the creation of two main elements. They are combined into a single system - a podium for the speakers and a folding part with which you get access to the luggage compartment.

Manufacturing

The base will consist of two sheets of plywood. Their sizes and shapes are almost the same. But only the bottom sheet will have slightly smaller cutouts for the folding element. In the end, the task is to build a stepped ledge on the base. It will become a support for the folding element.

1. Don't rush to remove the standard shelf. First, make a stencil using a piece of cardboard. The dimensions will be about 1.5 meters wide and at least 1 meter long.
2. Some people find ready-made drawings on the Internet, but they may not always clearly correspond to your specific luggage compartment dimensions. This is due to the fact that even at the assembly stage of VAZ series cars, certain deviations are allowed.

Manufacturing process

Place a sheet of cardboard on the factory shelf and make the necessary cuts

Pay special attention to the corners near the rear pillars. According to the markings, mark the areas through which the seat belts will extend. Creating a stencil will allow you to clearly determine the dimensions, dimensions and shapes of the future shelf. Based on the results obtained on the stencil, cut out the elements from plywood. Immediately check to ensure that the cut out elements comply with the dimensions of the vehicle’s interior. This way you can find mismatches, trim and fit the workpieces. Now you can dismantle the standard shelf, but leave the sides in place. On blanks from a sheet of plywood, make a cutout of the folding part, and cut holes for your speakers

Here everything depends on what kind of speakers you plan to install on your VAZ 2114. Using an electric jigsaw, a folding element of the podium is cut out on one of the blanks. To do this, you need to make a C-shaped base. The cut plywood element will become your folding element.

Holes for speakers

1. On the second piece, make the same cutout, only slightly smaller. So, when installing the first sheet of plywood on the second, a protrusion will be created at the cut site.
2. In the upper part, a connection is made with the cut out elements left on the folding element. This is done using furniture curtains.
3. Lay the top piece of plywood, where the folding part is already screwed, onto the bottom one. The two structural components are connected with self-tapping screws.
4. The resulting podium is covered with fabric or any selected material. Carpet, carpet and other similar materials are excellent.
5. The do-it-yourself podium is mounted on standard sidewalls. Check how firmly your shelf fits.
6. Now you need to fix the podium on the sides using self-tapping screws.
7. Don’t forget to first check how tightly the sidewall fasteners are tightened so that they don’t start creating unnecessary noise immediately after the work has been completed.

Even on standard sidewalls, a homemade thick shelf provides excellent sound quality for music, and also eliminates the noise that is familiar to VAZ 2114 owners, which comes from a standard podium.

Enjoying the result

A high-quality audio system is one of the main elements that owners want to see in their own car. This is especially true for the younger generation of drivers, some of whom are investing huge amounts of money in acoustics. Is it possible to trust the most powerful audio system on standard podiums? Of course no.

Making your own podium

If you have decided on the type and location of installation, you can start working. Making podiums for speakers with your own hands is not difficult.

Homemade speakers

Arm yourself with the following materials:

• plywood (for ring elements);
• fiberglass (for complex parts);
• epoxy resin;
• nylon or other synthetic fabric;
• leather or paint (for decorative work);
• putty;
• mounting tape;
• sandpaper;
• polyurethane foam.

Homemade speakers

In addition to materials, you will also need tools:

The template should be transferred to the material from which the part is being prepared. Cut the workpiece and drill the mounting holes. Place the blank in place and try it on. Also mark holes on the door and drill them. The parts are fastened with stainless steel bolts and washers.

We do it ourselves

If you try, the homemade podium will not be much different from the factory one. But the price will be much less. Plus an additional reason for pride.

To complete the work you will need a set consisting of:

• plywood (take a thickness of about 6-8 mm);
• PVA;
• epoxy;
• cardboard;
• degreaser;
• nylon tights;
• polyurethane foam;
• paints;
• putties;
• leather or fabric (will be tight);
• scissors;
• pencil;
• hacksaw or jigsaw;
• sandpaper;
• spatula;
• stationery knife.

I will say right away that in this case we are considering the option of making a homemade speaker podium, which will later be installed with your own hands in the front or rear doors of the car. Often a speaker with a diameter of 13 cm is used here. But no one bothers to make a design for the rear shelf.

But size is not key. The entire preparation procedure looks like this:

• think over the shape of the podium;
• take measurements of the speaker and its special protective mesh;
• the diameter of the ring here will be exactly equal to the diameter of the corresponding landing socket or place on the future podium;
• the external diameter of the existing ring we need, in turn, corresponds to the diameter of the tread (protective) mesh;
• a sketch is drawn on cardboard;
• the template is cut out;
• applied to plywood;
• outlined and cut out;
• a perfectly even hole is cut for the podium.

Do everything as accurately as possible so that no problems arise later.

If you are done with this, proceed to the next step.

Manufacturing process

You have already made the preparation. But it’s too early to relax. There is still a lot of work ahead.

• A layer of polyurethane foam is applied to the surface of the workpiece;
• The foam hardens, and the required shape is given with a blade or sharp knife;
• Next, apply 1-2 layers of putty;
• When it dries, make the product smooth using sandpaper;
• The product is painted in a suitable color;
• It is better to apply the paint in 3 layers;
• An alternative to painting is upholstery with fabric or leather;
• The banner is secured with glue.

The installation process finishes it all off. The most optimal method of fastening is installation using self-tapping screws on the inside of the existing door trim. This will preserve the sound quality, ensure reliable fixation, and at the same time definitely will not spoil the appearance of the interior and the podium structure in particular.

Do not forget to additionally use soundproofing materials. They are used to make noise on doors. This is not necessary, but it is useful and effective.

I think you have figured out how to make podiums in the doors. They can also be installed in rear shelves and racks.

The word “Podium” came to us from England and means elevation, convexity. An acoustic podium in a car is a special convex structure for mounting a speaker of any size. Owners of the domestic automobile industry prefer podiums to be able to install musical equipment of any segment and enjoy high-quality sound on the road.

Why install speakers on podiums

The first and obvious justification for the need to use podiums is that with their help you can move the dynamic head out of the standard seat if it does not fit there in depth. However, this is not the only reason.

For any speaker to sound, it needs a properly calculated acoustic design and a rigid base designed to dampen parasitic vibrations.

In home and stage systems, heavy, rigid enclosures are used that perform both functions at once. Subwoofers are made in a similar way for automotive systems.

The acoustic design of the mid-frequency speakers and “midbass” is formed by the design elements of the car. In this case, the cavities behind the casing act as the internal space of the sound column.

During operation, car acoustics experience significant vibration loads. If they are not extinguished, they are transferred to the sheathing panels and other structural elements, usually made of rather thin materials. These vibrations distort the sound.

The purpose of podiums is to absorb vibrations and dampen them. Prevent the spread of parasitic vibrations.

Making podiums for acoustics

VAZ 2114 acoustic podium and its production

Let's look at how to make podiums for doors. As a rule, the standard places on the doors of a VAZ 2114 car are designed to install speakers measuring 13 cm. What should we do if we want to install larger speakers? The most suitable material from which to make good podiums is plywood. And to start the process, you need to cut out circles of a certain size from plywood for the speakers you intend to install.

To adjust the podium to the desired shape, the following materials are used:

• Polyurethane foam.
• Epoxy resin.
• Compoplast.

And now everything is in order.

Frame making

Let's get started:

• We cut out the rings with a jigsaw so that the purchased speaker sits tightly in it.
• Using spacers from bars or self-tapping screws, we create a suitable frame where the speaker will be placed.

Spacers with different heights

Creating a Form

Acoustic podium VAZ 2114 and creating the form

Once the frame is ready, it's time to start creating the mold. The simplest solution is polyurethane foam. Creating a mold from polyurethane foam:

• We take the frame and foam it.
• We wait a certain time until the foam hardens. It may take more than one hour.
• After the foam has cooled sufficiently, we begin work that makes you feel like a sculpture. In other words, we cut out everything unnecessary.

• Apply a layer of putty to the foam and wait until it dries.
• Take sandpaper and sand the entire part.
• The acoustic podium is ready.

Creating a mold from compoplast:

Acoustic podiums on the VAZ 2114

The mold can also be created from compoplast. This is a two-component composite plasticine designed for almost any purpose. It has many useful functions: good adhesion, no shrinkage and toxicity, etc. So:

• Mix two equal parts of white and gray matter.
• Apply the resulting mixture to the frame.

The final stage of work

So:

• We stretch old and unnecessary nylon tights onto the workpiece so that there is no sagging.
• We dilute the baksu separately and cover the resulting form with it.

• We cover the product with anti-gravel, using one can for two podiums.
• The inner rings and foam walls can be coated with black spray paint.

• We fix the acoustic shelves to the door trim with self-tapping screws, doing this from the inside along the plywood.
• Next we hang up the original trim.
• We put the pockets in place.
• Install the speakers and enjoy high-quality sound.

Podiums for acoustics in VAZ 2114

Making acoustic podiums with your own hands makes sense if you need to get a unique shape. In normal cases, you can use ready-made options. When working, be sure to use step-by-step instructions, useful photos and video materials. Thus, the price of purchasing and installing an acoustic podium is significantly reduced, because you only have to buy consumables: glue, screws, etc.

Modern fashion for car audio

Today, most modern vehicles come with standard speakers. However, lovers of loud music in cars are often not satisfied with their sound, so they buy larger speakers. In this case, a different kind of problem arises - how to install large-sized equipment in the cabin so that, on the one hand, it does not disturb passengers, and on the other hand, to create truly clear sound?

One of the common ways to solve the problem is to make podiums for speakers. They can not only improve sound quality, but also take the performance of the speaker system to a whole new level.

A DIY acoustic shelf allows you to mount speakers of different sizes and shapes

What to do?

There are three ways to solve this problem. The choice in favor of one option or another directly depends on your requirements, wishes and sometimes financial capabilities.

Having a stronger and thicker shelf not only eliminates noise, but also improves the sound quality of the audio system. The thick shelf acts as a highly efficient enclosure.

Today we will look at how you can create an acoustic podium with your own hands, which will be placed on factory sidewalls. You can also try to make an option with your own sidewalls, but it is much more complicated and extremely difficult for a beginner to cope with. Let's not make things difficult for you. The option with standard sidewalls is very good.

Frame making

Acoustic podium VAZ 2113 and its production

The most suitable material for creating podiums is plywood. In addition, to give them the desired shape, you can use polyurethane foam or epoxy resin. This process includes several main steps:

The frame is cut out of plywood. Its thickness should vary between 2-6 mm.

• Using a jigsaw, you should cut out rings of a certain size. Actually, their size depends on the size of the speakers (see How to choose speakers for a car radio on your own). It is necessary that the speaker is fixed as tightly as possible with the ring.
• When creating a frame, spacers made of wood or self-tapping screws can be useful. Using spacers with different heights, it becomes possible to create an inclination of the podium.
• Carefully secure the structure using just a few screws. There is a possibility that the plywood will crack, so you should securely fix it to the surface, and then insert the screws with gentle movements.

Types and characteristics of podiums

Depending on the installation location, there are two types of elements: external and internal. Internal ones are installed if you want to preserve the factory appearance of the interior. For example, when replacing a standard speaker with a diffuser of similar diameter.

Internal parts are completely hidden under the door or ceiling trim. And it, in turn, should fit very tightly to the column. Otherwise you will get distorted sound. Internal structures are protected from damage and are easy to manufacture. And also, they do not affect the interior design of the cabin.

The external (external) podium makes it possible to install any speakers in size: 20 cm or 16 cm. The head can be placed with inclinations in different directions - towards the listeners or parallel to the door. External installation helps reduce vibration due to its tight fit to the door trim.

Main stages of the procedure

The process of installing and fixing any podium in any part of the car is as follows:

• Take a ready-made podium with a speaker built into it.
• The podium is screwed on the inside of the casing with self-tapping screws.
• However, to achieve truly clear sound, you will need to experiment with the installation - some screws will be tightened all the way, and some will not. That is, you need to give the podium such a position so that the speaker can reveal its sound to the maximum.
• It is recommended to soundproof the doors and ceiling (in this case you can achieve even clearer sound).
• After completing all the work, reassemble the ceiling, racks or doors (depending on where exactly the podium was mounted).

To enjoy clear and powerful sound in your car, there is no need to overpay for expensive speakers and factory-made podium elements. Most car enthusiasts are able to assemble a podium for the speakers in the car on their own from available means.

What are podiums

The acoustic podium is the base for the speaker, thanks to which it is fixed in the desired position. The podium serves as a speaker mount, for example, in a car door or pillar.

Those speakers that are built into the podiums give a completely different sound: richer and deeper, with clearly distinguishable high and low frequencies.

What are speaker shelves used for?

We can say that the podium performs several functions in the car interior:

1. the variety of appearance of the podiums helps to hide an unattractive sound system or emphasize the strengths of the interior design;
2. expands the acoustic capabilities of the speakers in the cabin;
3. podiums can be made from various materials and decorated with leather, wood, velor and other types of finishing fabrics to create a unique interior;
4. in complex-shaped podiums it is easy to place non-standard and large-sized speakers, for example, a horn.

What types of podiums are there?

Podiums are divided into only two types: external and internal.

External ones can be considered podiums that are mounted directly in the car interior - for example, on the rear parcel shelf. However, most often, car enthusiasts use internal podiums in car doors to better fix the speaker and improve the character of the sound.

Traditionally, most cars already have standard speakers or holes for them. Usually their sizes depend on the make of the car. Domestic cars typically have speakers with a diameter of 130 mm. Foreign cars can have built-in podiums of larger sizes - 160, 200 and even 250 mm.

Car door speakers are usually round or oval in shape. Depending on the car model, podiums must take this feature into account. In general, the shape of the podium can be absolutely any, since the main purpose of this element is to securely fix the speaker in order to give volume and clarity to the sound.

Round speakers of different sizes can be installed in the doors of any car

Advantages of acoustic podiums

VAZ 2114 acoustic podium

Podiums allow you to qualitatively improve acoustics, raising the sound to a new level. At the same time, you can not be limited to the standard landing dimensions of 13 cm, as provided by the manufacturer of the VAZ 2114. Among the many advantages of the podiums, I would like to separately highlight the following:

• Podiums allow you to install speakers (see How to choose speakers for a car radio yourself) in the car door. Thus, rear passengers no longer feel discomfort from strong sound, as was the case before. The sound will be evenly distributed throughout the cabin.

Podiums in the doors of VAZ 2114

• Podiums make it possible to create the correct direction of sound. As you know, sounds have a clearly defined direction. In other words, the higher the frequency of a sound, the more directional it becomes. This can explain the fact that the midrange and high-frequency speakers must be correctly directed.
• Podiums are always easy to install. Attaching them is quite simple and it is not necessary to cut through the metal of the door. Often acoustic podiums are firmly fixed to the skin.

Installing podiums is easy and simple

Note. You can evaluate the effect of “podium” sound immediately after fixing this element. Previously disturbing overtones will disappear, the transparency of the sound will improve, low bass will be added and the sound will seem to “get rid of” the speakers.

• Another advantage of the podium is the spaciousness of the “pocket” where a larger speaker can be inserted.
• Leather-wrapped podiums make it easy to remove dirt and dust.
• The podiums have petals on the base. This is also considered an advantage, since it will allow the element to be firmly fixed to the door.
• The podium will fit perfectly into the interior of the VAZ 2114, making the interior richer and more beautiful.

Final work

As noted above, the correct setting of the orientation of the speakers is considered a very important point, which will subsequently affect the creation of the podium frame. This includes focusing the beeper correctly, as well as listening to it. How correctly the speaker is adjusted, the music perception will be as comfortable as possible.

To accurately carry out the entire debugging process, you should start by setting the speaker, which is located near the driver, to the passenger’s left ear. Accordingly, the passenger speaker is tuned to the driver's right ear. Thus, a control point is reached in the cabin, where the sound waves intersect. This means that the music will evenly create a “load” on everyone sitting in the car.

If you plan to install component acoustics in the car, then the speakers are aimed at the rear view mirror, which is located in the cabin. As a guide, you can take an imaginary point located 10 cm in front of the passenger's head. This setting is especially important for fans of “heavy” music.

The design of the speakers implies the presence of a piston. Sound waves are generated by the movement of a diffuser, which compresses the air. When the waves exit the speaker, a vibration of a certain strength is formed. If the podium is not tightly fixed to the door, it will begin to vibrate.

Firstly, this will significantly affect the quality of the sound produced, and secondly, it can lead to deformation of the product itself. In addition, the metal on the door bends quite easily. The podium acts as a reliable speaker holder: the more rigidly it is fixed, the less vibration and deformation will be caused by loud listening to music.

Everyone chooses the shape of the podiums and the design approach to their production. But in any case, they must have appropriate rigidity. Therefore, when making a product with your own hands, you should use a durable frame. There is no need to rely on polyurethane foam, as it does not provide adequate rigidity.

To create truly high-quality music sound, you should remember that each car interior will “sound” differently. This depends on many features, for example, each surface has its own absorbing properties. Ideal sound is achieved by selecting the right audio equipment. Moreover, even an ordinary antenna requires proper configuration.

How to make podiums for speakers with your own hands VAZ 2114

Nowadays, stores offer a fairly wide selection of acoustic podiums from different manufacturers, but it is much better and cheaper to make podiums for the VAZ 2114 with your own hands. Moreover, it is not at all difficult.

To work, you need to prepare the following tools and materials:

• plywood;
• electric drill (or jigsaw);
• polyurethane foam sealant;
• epoxy resin;
• sharp knife;
• set of self-tapping screws;
• wood spacers;
• putty;
• nylon (you can take regular stockings or tights);
• bucks;
• black paint in an aerosol can;
• material for covering the podium. It can be genuine leather, dermantin, etc.
• sandpaper;
• anti-gravel aerosol.

Stages of work execution

1. Using a jigsaw, cut holes precisely to fit the diameter of the speakers.

If you don’t have polyurethane foam, but want to feel like a sculptor, you can use Comoplast. This is a synthetic material consisting of resins and dye. Compoplast is very plastic, safe for health, and odorless. Once hardened, this material resembles plastic. Compoplast is excellent for making an acoustic podium, as well as for minor repairs of various car elements.

To prepare a composite, you need to take 2 identical parts of the compoplast components and mix them thoroughly with your hands like plasticine. Knead for at least 3-5 minutes until the material acquires a dark gray color.

It is important to take exactly equal parts, otherwise you risk having to redo the whole job again, since the compoplast may not harden

Design of podiums for VAZ 2114

The plywood blank for the future podium should be “finished” properly. To do this, you need to pull the nylon over it, and the fabric should fit the workpiece as tightly as possible.

Now cover the entire area with the bucks solution. Ideally, baksu should be applied in 3 layers. Drying time for the first two layers is at least 12 hours. After applying the third layer, the workpiece should dry within 24 hours.

After which the product can be coated with anti-gravel. One standard can of anti-gravel is enough for an average of 2 workpieces. Paint all joints and inner rings with paint.

Painting the podiums of VAZ 2114

To make the car interior more exclusive and solid, you can use artificial leather or genuine leather instead of paint. Choose the color of the material to match the interior of the cabin so that the acoustic boost does not stand out too much and spoil the appearance.

Pasting the podium with vinyl leather

To secure the leather to the workpiece, self-tapping screws or construction staples are useful. Please note that some skill will be required in the process of fixing the fabric so that it does not go into waves in the future.

Manufacturing and installation instructions

Before you make podiums at home, you need to consider a few points. First of all, keep in mind that these devices must be made of wood, since this material combines well acoustically with an iron car body. If you have a shelf for a radio, you can also install wooden podiums in it.

Podium shape

The shape of the elements can be absolutely any - in this case it all depends on the imagination of the motorist. But when choosing a shape, you need to calculate everything, in particular, so that the podiums for the speakers do not interfere with the opening of the doors. When you decide on the shape, you will need to take a sheet of cardboard and draw it on it, and then cut it out.

Speaker platform

Designs with a platform for a speaker

1. Measure the speakers for the radio, as well as the protective grid. Draw a corresponding ring on the cardboard, taking into account that its internal diameter should correspond to the size of the place where the column will be installed. The outer diameter must correspond to the size of the protective mesh.
2. The resulting layout should be transferred to plywood and outlined with a marker or pencil. The thickness of the material from which the podiums are made should be about 7 mm.
3. Next, two shapes of the device are cut out, we proceed in the same way with the rings - the decorative part must be glued to the base, for a more reliable fixation it can be secured with nails.

Assembly of the structure

To assemble the ring, it is necessary to secure it well, for this you can use spacers. The spacers themselves can be made of any material; wood is usually used. As in the previous case, you can additionally use self-tapping screws for greater fixation.

Filling the podium

Filling the structure with foam

It is most convenient to work with polyurethane foam, but this option is not particularly durable; as an option, you can use epoxy resin:

1. Place the bag in the ring in advance (you will need it in order not to use excess foam).
2. The foam is applied in even layers from the base of the ring. When it dries, all unnecessary areas must be cut off. Use sandpaper to sand the podium.
3. Next, putty mixed with PVC glue can be applied to the structure, this will prevent crumbling. The putty itself is applied in several thin layers, each of which must be allowed to dry. When the material dries, the structure will again need to be sanded.

Features of fitting a homemade podium

The finished podium can be covered with artificial leather; this option is very popular today, since in its properties and visual appearance it is similar to door trim. As a rule, tension is carried out from the ring to the ends of the product, and each side must be tightened several times for better fixation. For greater convenience, you can use a hair dryer, and when the covering is finished, you can use a stapler for fixation. The excess part of the upholstery material must be cut off.

The finishing touch

Once the structure is ready, you can install it in a car door or shelf. As a rule, the device is fixed using self-tapping screws. Of course, before this you need to completely remove the door trim and speakers. After the podium is installed, you need to check the sound quality of the speakers - only when you understand that you are satisfied with everything, the structure can be securely fixed and the door can be assembled.

If you want to achieve the best sound, then it would be a good idea to soundproof your car - special noise-absorbing materials are used for this. You can also achieve high-quality sound by adjusting the acoustics.

Price issue

As for the price, it all depends on the manufacturer, the material from which the podiums are made, as well as the quality of the upholstery material. The average prices for podiums are as follows.

Features of choosing and installing speakers in Priora

The quality of music in a car is ensured by proper installation and connection of several speakers. The sound volume depends on the size of the tweeters. Many Prior car owners try to install podiums in the front, in the doors. The placement of the speakers is possible both at the top and bottom of the doors.

Leather interior of Priora

There are several important features when choosing tweeters for a Priora:

1. First of all, you should decide on their optimal size. It is not recommended to install elements that are too bulky. Since they take up a lot of space in the cabin and interfere with the driver and passengers. And it’s easy to damage strongly protruding parts.
2. The system should be conveniently mounted on the side pads. New elements must be placed on the surface of the door with the greatest precision. They must not block the pocket. Special podiums on the Priora, which are mounted on top of the sidewall next to the pillar, add new loud notes to the music. And also, surround sound transmission is added.
3. External design is also important. For example, in a black or gray interior it is better to purchase podiums of the same color. If there are two shades in the interior, one is selected: black or gray. Silver details are perfect for such palettes. They will add modernity and uniqueness to the decoration. A car finished in brown or beige colors is well complemented by a coffee shade.
4. Any additional installations in the cabin should not only look attractive, but also be of high quality. In addition, do not forget about convenience. No parts should interfere with driving.
5. Installation work in the machine must be carried out strictly according to the instructions.

And of course, all elements must be firmly attached so that the system does not fail soon.

Giving the basic shape

There is a known method in which blanks cut from MDF are placed on construction foam. We find this option extremely inconvenient. As the foam hardens, it tends to expand, so there is a risk of changing the position of the workpieces. But the main drawback is the labor-intensive process of cutting the foam to give the podiums an aesthetic shape.

For example, let's look at how to make podiums for speakers from MDF board, fabric, fiberglass and polyester resin. The podiums and door card will be a monolithic structure. To create a basic design you will need:

• make the necessary measurements. You need to cut a ring from an MDF board, the inner diameter of which will correspond to the outer diameter of the speaker housing. This way we will get a seat for the speakers. If you plan to place a pair of speakers next to each other, you can join them together at the stage of cutting out the slab. Please note that the structure must be strong enough, so the width and thickness of the cut out shape must be at least 10 mm;
• get rid of the protrusions on the door card that will interfere with the installation of the speakers.
• cut small pieces from MDF plates that will be used as stops for the rings. Please note that for best sound, the speakers should be positioned at an acute angle to the driver. Self-tapping screws can be used for fastening. If possible, use mounting angles;
• secure the rings. Carefully adjust the stops to maintain symmetry of the shape on opposite door panels.
