Do-it-yourself acoustic shelf for VAZ 2111-12

VAZ 2112 acoustic shelf

As you know, achieving good sound in a car interior, where there is very little free space, is quite difficult. But this can be done if you use some devices, one of which is a homemade or store-bought acoustic shelf. There are a lot of components inside a car that interfere with normal sound. It's not just the noise of the engine or the hum of a moving car. The weak stereo effect is mostly due to the rear speakers and the direction of their sound. In other words, a large number of barriers arise between the speaker and the listener, in which the sound disappears. Of course, the problem can be solved and this can be done in several ways:

Acoustic shelf VAZ 2112 with sides

Point sound. This method involves installing the speakers (see How to choose speakers for your car radio yourself) so that they are aimed directly at the listener. In order not to deprive any of the passengers of sound, this method involves directing the speakers to the center of the cabin, thereby avoiding obstacles.

Note. In this case, the speakers are installed on the ceiling using a podium. But this method has disadvantages. In particular, there is no way to firmly fix the speaker, which will lead to rattling and other errors. In addition, this method of installing the speaker risks a complete lack of bass.

Reflected sound. The speakers in this case are directed to the rear window. Thus, the stereo effect is enhanced, and the sound becomes much more voluminous. This method is much easier to implement than the first and the bass sound will not suffer from such a dislocation.

Note. The reflected sound method implies the presence of an acoustic shelf. Only the store shelf is made in such a way that the speakers face the ceiling, where some of the sound is dampened by soft and fleecy material. In addition, if the VAZ 2112 car has headrests on the seats, then these are additional obstacles. Therefore, it is recommended to make a shelf yourself, especially since it is not so difficult.

Rear trunk shelf of VAZ 2112 made of carbon fiber

This article will help you save money and make your own carbon fiber parts for the internal body elements of the VAZ 2112. The total cost of all materials used is approximately $150. This price includes three rolls of carbon fiber, 2 liters of resin, wax, a set of brushes and sandpaper. These are all the necessary materials to make a shelf for speakers. So, we have prepared the materials, now it’s time to get down to business.

The rear shelf of the VAZ 2112 is a rather voluminous element, and besides, there are simple curved lines, so we can make this part without any problems. First of all, we roughly sand the surface so that it can adhere to the surface of the shelf as best as possible. Next, we measure the required amount of carbon material. When cutting the carbon fiber, we add three centimeters of margin on each side, and also keep in mind that we will have to fold the material at the edges so that the seam is not noticeable. When bending the fiber, you should secure all parts of the part with tape or insulating tape, so it will not slip. We try on the carbon fiber and make sure that it fits the surface and does not bulge anywhere. In several places we grab it with pieces of double-sided tape to the surface. During the application of resin, the fiber may separate from the shelf, creating a risk of bubble formation; the tape prevents this from happening.

We mix all the resin, each type has its own instructions and hardening time, before starting work it would not hurt to familiarize yourself with this information. The resin will begin to set in about 15 minutes, do not mix more than you can use in that amount of time. We strongly recommend using a respirator while working, otherwise you will get headaches. Now we begin to apply the resin to the carbon using the “peck” method on the first layer. Make sure that the carbon fiber does not slip, you need to work carefully because this happens very easily. We continue to treat the carbon with resin until it completely saturates the fabric and the air is completely released from the fabric. We wait until the first layer dries, this lasts about 2 hours. Next, take scissors and cut off the excess material. The next step is to apply another layer of resin. At least 3-4 layers of resin must be applied to the surface. Subsequent layers can be applied using normal brush movements and a thicker layer of resin. There is no need to sand between coats; this will do more harm than good. At the last stage, do not forget to add wax to the resin. Its quantity should be twice as much as the hardener. After the last layer has been applied, you need to let the part dry thoroughly, this will take about a day. The part will have a slightly cloudy appearance after drying, but do not be alarmed by this. The last crucial stage remains; it determines what the element will look like. We begin polishing the trunk shelf of a VAZ 2112, starting with sandpaper with the coarsest grit and ending with a final size of 1500.

I was tired of the constant rattling of the rear shelf and so I decided to get confused and made a new shelf with my own hands

and so we take two pieces of plywood like this...

and cut out something like this. In order to cut it out, we take the old shelf and lay it on top of the plywood that is above in the photo, outline it with a marker and use a jigsaw. I made two such templates, the second one is about 1 cm narrower, along a curved arc that is located on the glass side. I did this because there will be fewer adjustments in the future

this is how it turns out, two cut pieces of plywood

try it on. We make the smooth edge of the plywood flush with the reinforcing strut of the body. if it sticks out, we cut off the edge of the glass, but don’t get carried away so as not to overdo it

After making adjustments on site, we take the first measurement from below, insulation on it, and the second cut plywood on top. We mark, use a thin drill to make holes so that the self-tapping screw fits better, and tighten them tightly in a circle. This is done so that it is stiffer and does not rattle

marking the places for the speakers...

but here it’s up to everyone... I decided to paint on both sides. This is the outside side, that is, from the trunk. and one more thing, if you decide to paint, then before painting you still need to go through the screws; in the next photo you can see exactly where. We pass the edges with sandpaper and sand until there are no sharp edges

Photo instructions for making side shelves in the trunk of a VAZ

The resulting design can now be installed in a car. When installing, the standard self-tapping screws for attaching the sidewalls to the body must be replaced with M5 bolts. In order for the acoustic shelf to sit firmly on the sides, it is best to use Velcro (see photo below).

Now, significant weight can be placed on the resulting hard modification of the sides of the trunk without fear for its integrity, plus with this design we have completely eliminated any rattling and squeaking.

There are many other ways to combat noise in the trunk of a VAZ 2111 and VAZ 2112, but it is best to use them in combination - this increases the effectiveness of using each of them separately.

On all cars of the tenth family, including VAZ, installing the front speakers in standard places is possible without any difficulties. This is especially easy to do if you already have wiring for powering the speakers. In this case, there should be no problems with the installation at all. One important point is worth noting. So, first of all, we remove the casing, after which we find the power wires for the speakers and connect them. After that, in all 4 corners we install square brackets-clamps under the self-tapping screws, which will then be used to secure the speakers. Next, everything is assembled in the reverse order, that is, we install the casing and the procedure can be considered complete. All rights reserved.

Acoustic shelf and its production

Acoustic shelf for VAZ 2111

The reader probably wondered if it was possible to make such a product yourself without spending extra money. The answer is, of course you can. Just know that the acoustic shelf for the VAZ 2111 or 2112 should be built according to a slightly different scheme. The fact is that these car models belong to the station wagon body type, and most of the instructions for making shelves that can be downloaded from the Internet imply installation in sedans. In principle, the manufacturing process does not have any special differences, but there are a number of nuances that should not be ignored, otherwise it will affect the sound quality of the speakers and even the safety of passengers.

Installation of devices in rear doors

Compared to installing products in a shelf, installing 16 cm speakers directly into the rear doors is more labor-intensive. First, the owner of the LADA Granta will need to remove the door trim. The “Standard” package does not provide for cable lines throughout the cabin, so you will need to lay them yourself. The wire leads end under the front panel.

Other versions of the Lada Grant have the ability to quickly connect speakers to existing wired lines without much difficulty.

How to install step by step? The installation procedure assumes the following sequence.

Loudspeakers are screwed to a pre-prepared plywood cover.
The corresponding ends of the wires present in the door panel are connected to the speaker terminals in the LADA Granta car.
The trim is fixed to the door using appropriately sized self-tapping screws.
We cut a hole in the door trim to match the diameter of the purchased mesh.
The mesh should be attached to the upholstery, which can later be installed on the door panel.

VAZ 2111 station wagon

A station wagon or hatchback differs from a sedan in the size of its interior. Because of this, it is necessary to place acoustic podiums with the correct direction on the station wagon shelf. There are other nuances, including mounting options, and much more.

Finalization

Refinement of the acoustic shelf

In the VAZ 2111, the shelf does not have to be made from scratch. You can simply modify the standard one. Here are some features you need to know:

The standard rear shelf on the VAZ 2111 does not allow the installation of speakers, since it does not have a straight surface. The point of finishing is precisely to create a flat surface;
The material for finishing should be plywood 20 mm thick. Let its width be about 3.4 meters;
The standard shelf consists of two layers, the material of which resembles plastic. It is easy to cut with a knife.

Taking these features into account, we do the following:

We cut off the part of the shelf where we intend to install the speakers;
From a piece of plywood we cut out the outline of the shelf, copied from the standard one;
We coat the plywood with epoxy and glue it on the back side of the shelf;
The seams and irregularities formed during the joining process are eliminated with acrylic wood putty, and then, after drying, sanded down with sandpaper;
In the end, you will need to reupholster the shelf with a suitable material, for example, carpet.

Note. A piece of plywood can be glued not down the standard shelf, but up. There won't be any difference. But, in both cases, the standard shelf will become noticeably heavier, and the speakers will hold more confidently and reliably. By the way, if the shelf after such modification is, in your opinion, not weighted enough, there is a reason to cover it with vibration material, and only then reupholster it with carpet.

Shelf from scratch

Acoustic shelf from scratch

If you are not satisfied with the modification, but want to make everything yourself, then we do the following:

We take two pieces of plywood. The first piece should repeat the shape and dimensions of the standard shelf, and the second piece should be 1.5-2 cm shorter;
We connect two pieces of plywood together using foam or glue. And then we make sure to fasten it with wood screws;
We separately manufacture the folding part of the shelf. It can also be made from plywood. Awnings work well as a tilting mechanism.

Note. The folding part of the shelf can be cut off from the standard one, and then screwed to the new one. Nothing complicated - we cut off exactly the part with the hinges and attach it to the new shelf.

At the final stage, the shelf must be covered with carpet.

Note. You can make a shelf without a folding part, using one sheet of plywood. To give it a stylish appearance, you can decorate the shelf with an inscription, by burning, or in some other way.

Hyundai Accent › Logbook › Actually, something that has been standing for a long time. Acoustics in my car.

So I decided to write what was actually done regarding the sound in the car during the two years of ownership. First of all, when I bought the car (it had a cassette radio), it was decided to buy a new radio. It was decided to buy an inexpensive mafon with three outputs for amplifiers, for subsequent connection of all components through amplifiers... I arrived at a local Pioneer store and chose this from everything that was offered to me:

Before: Art Sound AS 6.2 (left over from my eight) the cost was about 4500 rubles.

Since spacers had to be placed under the front, it was decided to make the front doors noisier. The material used was vibroplast STP + splen from the same company. There is no photo of the process, there is only the final result:

I am pleased with the result of the door noise. The noise became a little less, the door closes with a slight movement of the hand, the sound when closing is dull... In general, everything is as it should be... Next in line was installing the “pancakes” back. For these speakers, I made an acoustic shelf from 20mm plywood and covered with gray carpet. There were no problems with the shelf. I did this: I took off the original shelf, put it on plywood, traced it and cut it out. Next, so as not to miss the holes for the speakers, I put the cut out shelf in place as it would stand and from the trunk side with a marker I traced along the original holes in the steel shelf... And only then, based on these marks, I tried on the speakers, how it would all be, marked it out and cut it out . I tried everything on, was glad that it worked the first time and didn’t screw up anywhere and covered it with carpet... The most difficult thing was to connect the shelf with the speakers already in place))) Because. The shelf with the speakers already screwed in would not fit through, and if I first put the shelf down and then screwed in the speakers, I couldn’t get a screwdriver under one screw... In the end, I don’t even know how, I managed to crawl up and screw the speakers onto the shelf already in the car... The shelf itself I screwed it with self-tapping screws of the required length through the holes of the steel shelf through the spacers between the steel and acoustic shelf. Overall I'm happy with everything. The bottoms on the pancakes were very pleasing... I didn’t think it would be so good. Many who rode behind me asked what kind of subwoofer I had... And this is without an amplifier.

Then, about a year later, I found out that a friend had an unnecessary Mac Audio amplifier, but he didn’t want to sell it separately, but sold it together with a Signat 12″ sub and a 2 farad capacitor for 3000 rubles.

The case was, to put it mildly, not a fountain... And having acquired the whole thing, I decided to make a new case for it. This speaker was tested on the car audio website, here is a link to the article: www.avtozvuk.com/az/2004/…/htmdoc/120-145signat. htmFrom which it became clear that the housing for this speaker must be at least 30 liters, there is no more sense. I wanted to make the housing with minimal loss of trunk volume, but with the required displacement. I measured everything in the trunk that I needed and went to look on the Internet for how to calculate the housing for a subwoofer... in the end I calculated everything on an online calculator. There you enter the dimensions of the sides that you need and he gives you the displacement that you will receive in the end. Now for some reason I can’t find this site... But I didn’t save the link...(((For the body, 20mm liquid nails, wood screws (were), soundproofing material Biplast Premium, and naturally dark gray carpet were purchased. All joints before tightened with self-tapping screws, were coated with liquid nails, and also inside and outside, all joints were again covered with the same liquid nails. When the body was almost ready, Biplast Premium was glued on the inside

Next, I closed the case with the front wall and glued it onto the same Biplast Premium. Then I covered everything with carpet. It was decided to attach the amplifier to the back wall of the subwoofer, and the capacitor to the side. I bought the wiring as a ready-made Mystery kit:

And I routed everything on the driver's side. The power wire was pulled from the engine compartment through a wiring hole with a rubber membrane. As a result, in the trunk it all looks like this:

Overall, I'm happy with the sound at the moment. Everything was set up so that the sub would simply play along with the music exactly as much as I considered necessary. The goal was not to destroy the glass on neighboring cars and houses, as well as my own ears... As a result, the amp was turned up almost to the minimum, and the bass was soft and pleasant. In general, I am very pleased with how everything turned out in the end...

Thanks to everyone who mastered so much text!))) I wrote from the heart))) If you have any questions, ask, I’ll try to answer)))

Technically, installing music yourself in Lada Vesta is not difficult. By adhering to a few simple rules, any motorist can handle the work. Consider these rules:

All work must be done very carefully to avoid damage to the plastic upholstery;
The car already has audio preparation; you only need to install harnesses to connect the front speakers;
You cannot cut off standard connectors, but you need to buy and use adapters;
Before installing audio, it is recommended to soundproof the Lada Vesta doors to obtain improved sound characteristics;
Install the speakers on the spacers.

Audio preparation is measures carried out by the manufacturer (laying audio cables, installing speakers, etc.) that simplify the process of installing music for the car owner. Depending on the configuration of Vesta, audio preparation may be different.
