How to remove the rear shelf of a Lada Granta to install speakers with your own hands

After purchasing a car, it is often necessary to modify some of its components, elements, and mechanisms. The reasons are the most banal: upgrading the audio system, installing additional speakers, a subwoofer, etc.

Standard designs do not allow placing a row outside the factory components. Depending on the complexity of the task, we carry out the Lada Granta upgrade both independently and with the help of workers from a specialized studio.

Making a shelf with your own hands

Ready-made panel for high-quality music

Auto mechanics recommend installing a wooden shelf for acoustics in the Lada Grant. This product significantly improves sound quality by using the trunk volume as an acoustic closed box. In this case, the speakers are installed on top, and a decorative grille is mounted on them. The brake light can be removed from the car's standard shelf.

Many Lada Granta car owners make their own acoustic shelf. For this you will need:

First of all, the ceiling of the product is made. First, the Lada shelf is outlined on cardboard, then the diagram is transferred to plywood. The side that will be located near the window is cut out obliquely, its ends are ground down.

To ensure that the resulting product matches the dimensions of the rear of the car, calculations are initially carried out. To do this, you will need to measure the standard shelf. A sketch of a homemade design is made taking into account the data obtained.

The next step is cutting out the holes for the speakers. The radio can be covered with fabric. Often they make a pocket in which various things will be stored. To do this, you will need to cut an vent in the ceiling of the shelf. Then the remaining parts are glued together. Drying such a shelf lasts no more than 24 hours. Now the product is ready for finishing work. The shelf is covered with carpet or other fabric. It is necessary to take into account that the fastenings must be located near the Granta rear seat latch.

Speaker installation

Many sedans are purchased in a classic configuration, without a radio and sound system

To install these fragments, it is important to follow the step-by-step instructions:

1. The casing is removed. To do this, unscrew the handle, which is held on by two bolts, disconnect the latches and pull out the panel covered with fabric. Sound insulation is removed.
2. The electrical wiring is disconnected, the old speaker is removed (if equipped).
3. A hole is created in the cladding for musical equipment. An iron niche has already been created for size 13 acoustics. This is where the back of the speakers is inserted. Sometimes a little filing with a jigsaw is required.
4. The equipment is fastened with self-tapping screws. The wiring is being connected.
5. The facing card is returned to its place and secured with clips. They often break during removal, so it is worth purchasing an additional set of clamps. At the end the handle is screwed on.

Sound insulation installation

Sound insulation of car interior

An important point in the manufacture of an acoustic shelf is its sound insulation. The standard product does not provide sound insulation.

First, it is recommended to lay some kind of vibration-absorbing material, for example, vibroplasts, ECO, and visa mats. The sheet will need to be cut into pieces of the desired size. Using a hairdryer, the material is heated and rolled out onto the shelf. A hard roller is used for this. The absorbent material needs to cover 60-100% of the shelf area.

The second layer is sound-absorbing material. It could be “Isotone”, “Accent”. This material covers the entire shelf area. Please note that the sound insulation layers should not be thick, otherwise installing the shelf will not be possible. The entire complex of these works is aimed at reducing noise from the trunk and rear arches and improving acoustics (if the speakers are in the rear parcel shelf).

What should be the power of good speakers?

When analyzing the concept of speaker power, it is worth remembering that the value of this indicator should be slightly greater than the outgoing power of the car radio. Otherwise, all attempts to obtain more or less high-quality sound will be reduced to zero.

Video: how to find out the power of the speakers

Typically, speakers are labeled with a rated and peak power rating, with the former indicating the power at which the speaker can be operated for long periods of time without the risk of damaging the cone or overheating the coil, and the latter indicating the maximum power the speaker can withstand for a short period of time. .

Audio system installation

When buying a Lada Granta, a car enthusiast cannot always determine whether the vehicle is prepared for the subsequent installation of an audio system. Typically, such a system includes simple speakers with average sound quality. However, this option rarely satisfies drivers.

Lada Granta is quite well prepared for the installation of modern audio systems. This preparation includes having the necessary wiring to connect the car radio and speakers. To carry out this work, you will need a screwdriver, bits, edges, a knife and insulating tape.

Before installing the acoustics, you need to turn off the power to the vehicle. To do this, remove the minus terminal from the power supply. Please note that the antenna is often installed in the upper right corner of the windshield. A place for it is cleared in advance.

The electrical wiring must be routed under the dashboard to the glove compartment. There is a small plastic trim on the right side of the glass that will need to be turned off. The modern antenna is equipped with an excellent self-adhesive panel that can be easily and quickly mounted to the windshield. In order for the antenna surface to bond well with the glass, you will need to degrease it. A special tool is used for this. A similar technique is used when installing speaker systems on various brands of cars.

The next step involves installing the main instrument holder. Before installation, the serviceability of the radio is checked. To do this, you need to turn it on and listen to the radio station.

To ensure the speakers are installed correctly, first remove the door trim. To do this, glue a special ESP connector located on the back side. The manufacturer took care of the presence of an opening with a diameter of 30 cm for the speaker. Speakers are installed in these places. The final stage is to turn on the minus terminal and tighten the screws.

Acoustics for the front doors of Lada Granta

Installing speakers in Granta doors allows you to be independent of the body type - speakers in the doors do not require an acoustic shelf. This means that you can install speakers in a sedan and a hatchback according to the same principle.

Preparatory work

Before we begin the installation itself, let's figure out how to prepare the car. For this:

• We disassemble the door : dismantle the handle (pry up and remove the trim, unscrew 2 screws), the tip of the limit switch, two screws from the bottom of the door, overcoming the resistance of the retaining pins, pull the door card toward you and remove it from the door;
• We soundproof the door: in the warm season or in a heated garage, we cover all accessible parts of the door with vibroplast. Vibroplast StP M2 is suitable; when applying it to the door, be sure to heat it with a construction hairdryer and roll it with a pressure roller;
• If you have Spleen thermal insulation material, we cover the inside of the door card with it. This will further hide noise from the door when assembled;
• We are preparing spacers , if any are required for installing 16 cm speakers - more about them later in the text;
• We replace the factory terminals on the speaker wire in the door with normal ones (usually good terminals are included with the speakers) - to do this, we simply cut off the unnecessary connectors and attach the terminals we need to the wiring. A high-quality twist with heat shrink is enough;
• If the door panels do not have holes for speakers , we prepare them. It would be optimal to supply factory acoustic grids, which are installed on luxury versions of Granta and Datsun OnDo.

Installing speakers in Granta front doors

The standard acoustics in Grant are 13 cm speakers. They do not produce good sound, but they are easily installed in the factory holes for the speakers without unnecessary manipulation. The procedure for dealing with them is simple:

• connect the speaker cables, observing the polarity;
• fix with screws in regular places in the metal of the door or directly on the door card;
• install grids (in common parlance - grills).

An important disadvantage is that the center of the mounting hole and the place under the grill do not coincide. This means that when installed with complete grills, they will look asymmetrical and clumsy.

Standard acoustics most often do not produce a rich sound and, when installed with their own grids, look poor.

How to install 16cm speakers with spacers

In pursuit of sound, it is logical to install 16 cm speakers. This is where all the disadvantages of the AvtoVAZ design appear - the speakers either are not centered, or do not allow the window to roll down, or interfere with the glove compartment lid.

Why are spacers needed ? In order not to cut the door, if you do not put the acoustics in the spacer rings, you will have to attach it to the metal of the door. This may result in the need to cut the door itself in order for the speaker to fit in, and is dangerous for the glass.

For this reason, speaker rings made of plywood are attached to the metal of the door, and the speaker itself is attached to them.

The procedure is as follows:

• we make or buy spacers for speakers - thickness 10 mm, material plywood;
• cut a hole for the speaker in the card and mark the installation location along it;
• put the spacer on 4 self-tapping screws;
• We install a column in it - observe the polarity!;
• install the map + install the standard mesh so that it doesn’t interfere with the glove compartment.

If the spacer bursts during installation, this may result in a rattling noise coming from the door while driving.

What speakers are better to put in the front doors instead of standard speakers?

We recommend the Pioneer TS-G1733I model. At a price of about 2 thousand rubles, they are freely installed through spacers in Granta doors without cutting metal and do not interfere with the glass. Easy installation will save you nerves and time.

Preparatory work

So, if the owner has firmly decided to upgrade on his own, then we prepare the following:

• set of automotive tools;
• new shelf, insert;
• speakers (optional);
• blocks with electrical wires for connecting to the central power circuit;
• other components at the discretion of the owner.

The shelf on the Granta sedan is located behind the rear row of seats. By default, the design does not have holes for speakers. This is precisely the stumbling block for many owners.

How to install 16 cm speakers with spacers

You can install 16-cm speakers without enlarging the hole, but then, due to the spacer, the speaker will stick out from the door. It is more advisable to carry out a standard cutting. Instructions:

1. After the handle and facing panel are removed, the wires are disconnected. Sound insulation is removed. Use a jigsaw to enlarge the standard hole in the door.
2. A pre-created podium is attached to the back and securely fixed with self-tapping screws.
3. The cable is removed, the electronics are connected, and the structure is assembled in the reverse order.

Before putting the door back together, it is important to check the sound of the speakers. Incorrect operation may be due to incorrect wiring connections

If you hear wheezing or knocking, it means the speaker is not securely fixed.

The process of removing and installing a shelf

• We place the car on a flat platform, open the rear row of doors to provide full access to the shelf;
• lower the backrest of the rear row of seats;
• unfasten the seat belt fastenings, having first unscrewed the fastening bolts;
• unscrew the fasteners for the child seat;
• use a screwdriver to pry up three plastic latches;
• pull it towards you and remove the plastic shelf.

Finally, we install the new one and assemble the components in the reverse order.

Some points of sound insulation

You can increase the level of noise and vibration insulation in various ways. If we are talking about a standard design, then they practice pasting with felt fabric on the outside / underneath.

When it comes to a liftback shelf, it is already soundproofed from the start; there is no need for additional noise reduction.

We’ll look at how to remove the Grant liftback trunk shelf below.

When installing custom shelves, they are soundproofed by default during the manufacturing process.

Which speakers are the best?

To determine the best speakers, they will need to be nominated depending on the type.

Coaxial

1. Pioneer TS-1339 - a large number of car enthusiasts recognize these speakers as the best. Their size is 13 cm, which allows you to install the speakers in specially designated places. They produce clear sound and correct bass, transmitted without distortion. If your sound requirements are not very picky, then these speakers are the best choice, as they have an affordable price and acceptable characteristics.
2. Morel Tempo Coax 6 – the ability to create a two-way system with unique sound quality. Sound comfort is achieved by turning the “tweeter” by 20 degrees. The soft dome of the tweeter and its low resonance level are the conditions for reproducing frequencies over a wide range. The positive aspects of this system include power, as well as optimal sound balance and the fact that there is virtually no distortion. At the same time, low frequencies lack the so-called velvety sound.
3. The JBL GTO-938 delivers serious sound power as a hallmark of these speakers, which also feature high sensitivity. They have an oval shape, which contributes to a stylish design. They are distinguished by balanced frequencies (high and low).

Component

1. Morel Tempo 6 is a full-fledged acoustic system, characterized by high technical parameters and high-level assembly. Its configuration includes 2 tweeters, 2 crossovers, main speakers and a bonus in the form of an additional bowl. Highly detailed sound.
2. Focal Performance PS 165 is a phenomenal sounding system that guarantees balanced, rich sound. Suitable for use as front speakers. This brand produces truly high-quality speakers that can satisfy the needs of even inveterate skeptics.
3. Mystery MJ 105BX is one of the best speakers among its kind. Affordable price, high technical characteristics and excellent sound. The advantages of this cabinet speaker include its compactness and ease of installation.

Reviews

Conclusion Removing the rear shelf on a Lada Granta is not at all difficult, it will take ten minutes of free time and you’re done.

Installing a tuned version of the insert is also not difficult for the average driver. If you don’t have free time, you can always contact a specialist service center. Now the owner knows exactly how to remove the Grant shelf with his own hands.

Reliable fastening

The purity of the sound depends not only on the speakers and receiver, but also on the conscientiousness of the technician installing the acoustics. The stronger the midbass is installed, the better. He doesn't need any extra vibrations! If the speakers are installed in doors, spare no expense on noise and vibration insulation (of the doors). Then the doors won’t rattle at high volumes, and the bass will sound much better. If you decide to install the speakers backwards, remember that there must be enough free space between them and the subwoofer (if you install one). The best solution in this case: speakers. in the rear doors, subwoofer. in the trunk.

If possible, ?query? receiver and amplifier directly from the battery to avoid interference, wheezing and sound distortion when the engine is running. But the wires that come from the “head” to the speakers, contrary to popular belief, they do not have a special effect on the sound quality. Only a true music lover can notice the difference in sound, and only if the audio equipment installed in the car is of very high quality. Therefore, it makes sense to replace the “standard” ones included in the kit. wires are special “gold plated” No. A special set of wires is required only when equipping a car audio system with an amplifier. But even in this case, buy very expensive “cores”. not worth it.

Where is the ?ringing??

It is advisable to install mid- and high-frequency speakers in the front part of the cabin. There should not be so-called rear speakers in a car. Put the acoustics back. It's like listening to an orchestra with your back to the stage! For proper sound in a car, good front speakers and tweeters are enough. in the A-pillars. It is advisable to connect them as close to the “midbass” as possible. However, this is often very difficult and requires a global rework of the interior trim. Therefore, install “high-frequency” speakers. near the mirrors, in the lower part of the A-pillar.

The direction of the tweeter (to the cabin or to the windshield) is determined by ear during preliminary connection. If the standard seats of the car do not allow installing a 6-inch speaker, then you can buy a ready-made “podium?” (usually available for sale for VAZ cars), install the speaker on an adapter plywood ring or order a podium from a specialized studio.

The only acoustics that can be placed in the rear are . subwoofer. The direction of low-frequency sound, unlike higher ones, is not picked up by the ear, and such a placement of the subwoofer will not affect the sound quality. How to choose the right subwoofer for your car If you are determined to achieve the best sound in your car, you cannot do without a subwoofer. The subwoofer ensures deep, loud bass, making the car's acoustic design complete and impeccable.

Many reputable magazines talk about subwoofers, test various models of famous brands, choosing a winner from them

But is it so important for the average consumer that a certain subwoofer received the highest score as a result of the tests? After all, they mainly test models from such giants as KENWOOD, PIONEER, SONY, not to mention manufacturers of Hi-Fi equipment. MTX, JL Audio, etc.

They are so good that the average ear simply cannot feel much difference in their sound. So, if you are not going to participate with your car in competitions for the best car acoustics, then the cost of music in the car should not exceed 20% of the cost of the car.

And no matter how connoisseurs of good car audio resist. The starting point should be the car. It’s hardly worth buying a powerful, expensive subwoofer in order to voice the already singing details of the interior of a domestic product. Therefore, it is recommended to use this standard system for calculating the cost of installing equipment for many: if the car cost $1,500, you should not spend more than $300 on music. those same 20%.

Subwoofers

There are two types: active and passive. Active subwoofers, unlike passive ones, have a built-in amplifier. At the same time, you are sold a certain set of “instant preparation and ready-to-eat”, i.e. you just need to connect two contacts from the head unit, and the system is ready to work. In this case, there is no need to coordinate components (head unit, amplifier, subwoofer).

However, active subwoofers have their drawbacks, namely: their manufacture uses simpler and cheaper components, which inevitably affects the sound quality. To connect a passive subwoofer, you must select an amplifier that, when bridged, provides the same power that is indicated in the passport of this subwoofer as nominal.
