Manufacturing and installation of an acoustic shelf on a VAZ 2114

Having a hatchback body, the VAZ 2114 is distinguished by an impressive trunk, which covers the entire rear part of the car. It is separated from the interior by a seat and a removable shelf.

The shelf has bending points provided by the design, along which it folds, increasing the volume of the luggage compartment. This design does not cause any complaints, especially if the presence of music is not important, but if music means a lot to the owner, a “surprise” awaits him - there are no places for mounting an audio system in the design of the VAZ 2114.

The standard shelf is thin and light, any speaker will make it heavier, which will lead to its incorrect fixation, the shelf will rattle a lot, the audio system will resonate with the pits and the rumble from behind will be simply unbearable, the presence of such “music” is very doubtful pleasure. Later, the sides will also become loose, and then it will become completely unbearable.

The problem is solved in three ways:

1. The shelf is removed, there are no rear speakers, there is nothing to rattle, but there is no music either.
2. Acoustic shelf VAZ 2114 is inexpensive to buy, but it will improve the situation significantly.
3. Make an acoustic shelf yourself.

In addition to eliminating third-party noise, the acoustic shelf will solve the problem of trunk structural rigidity, provide the acoustic system with a reliable frame, and eliminate the negative impact of acoustic vibrations on the mechanical joints of the rear door and trunk as a whole.

We are finalizing the factory version

If the VAZ 2114 acoustic shelf is expensive for you, but you don’t want to make it yourself from scratch, then you can modify the factory shelf.

To do this you need the following tools and materials:

1. Plywood.
2. Putty.
3. Upholstery.
4. Self-tapping screws.
5. Epoxy adhesive.
6. Jigsaw.
7. Knife.
8. Emery (sandpaper).
9. Stapler.

The shelf is easy to modify; for a good result, the steps are performed in the following order:

1. We draw a template on cardboard, use it to draw places for the speakers on the shelf, and cut them out with a jigsaw.
2. We use the shelf as a template, draw what we need on the plywood, and cut out what we need on the plywood.
3. Using epoxy glue, we glue the shelf to a piece of plywood cut out for it.
4. We cover (glue) the finished result with carpet (another fabric), not forgetting about the plywood ends.

Such a shelf, due to its rigidity, will significantly improve the sound, but in addition, you can soundproof the trunk and the shelf itself, this will make the music even better.

For soundproofing the following will be useful:

1. Bitomast and Vibroplast (1 sheet each).
2. Smoothing tool (usually a roller).
3. Construction hairdryer.

Due to the fact that vibroplast perfectly dampens vibrations, it is enough to cover 2/3 of the trunk with it. Bitomast is applied to the shelf itself; it is a noise-absorbing material, it improves the sound and removes vibration echoes and unnecessary sounds. To apply, the materials are laid out on the desired surface, then heated with a hairdryer and rolled out over it.

Carefully monitor the quality of rolling; if there are bubbles under the material, the results of your work will very quickly fail.

Installation sequence

The sequence of actions when installing speakers on the rear parcel shelf of a car:

We recline the seats for easy mounting. We remove the rear brake light, which is located on the rear shelf: to do this, first unscrew two self-tapping screws. We use a marker (any kind) to outline the future holes for the speakers: you can choose any convenient method for yourself as “marks”. Removing the side struts

If you have a car with side curtains, then you first need to secure the plug, remove it and only then unscrew the screw under it. We remove the airbag with extreme caution. We remove three clips from the shelf and take out the structure itself. The work with the shelf is completed, now we start working with the wires:

The work with the shelf is completed, now let's start working with the wires:

We remove the side posts so that the wires can be connected. Take care in advance to make the necessary holes for the diameter of the speakers. We connect the wires to the speakers and wrap them with electrical tape. We run the wires under the plastic. Let's put the structure back together: pay attention to the safety of all wires.

If installed correctly, the speakers will not make noise even on a bad road. On the contrary, they will improve the sound quality of the music and immerse you in the atmosphere of your favorite tunes.

You can buy car speakers with delivery in Kyiv, Kharkov, Odessa and Dnepr, and also install them in the rear parcel shelf at 130.com.ua.

We make it from scratch

The acoustic shelf of the VAZ 2114 is easy to make with your own hands, you will have to spend a little on materials, and do not regret a little of your time.

The following “ingredients” will be useful:

1. Centimeter chipboard or MDF.
2. Carpet (other fabric).
3. Glue.
4. Self-tapping screws.
5. Jigsaw.
6. Drill.
7. Grinding machine (emery, sandpaper).
8. Stapler.
9. Materials for the layout: cardboard, pencils, drawing supplies.

We will do it like this:

1. We are preparing a template, then we will try it on the car, it should be a little larger.
2. We cut out the shelf according to the template, remove the irregularities by grinding down the gap included in the template.
3. We double-check its dimensions on the car, if everything matches the car and the size of the intended speakers, then the shelf is ready.
4. We are preparing materials for covering (pasting), everything should be at hand.
5. Apply glue to the plywood, apply fabric, and roll everything out to avoid bubbles.
6. We fix the edges with a stapler.
7. Let it dry for a day.

In order for the shelf to be foldable, you need to take care of the moving elements in advance and try on the hinges. It is better to do this before pasting with carpet, so the design will look much more aesthetically pleasing; the moving technical gap can be closed with a strip of “elastic” (elastic fabric), but not with carpet or other non-stretchy fabric.

Very often, people don’t want to fool themselves with jigsaws and glue, so they immediately buy ready-made ones. This solution has a significant advantage, because there are a great many modifications of shelves, both a regular “plastic shelf” and a solid “VAS 2114 acoustic shelf with sidewalls” are sold, all intermediate options are also present in the online assortment. Although the purchased version will be many times more expensive than the homemade one, laziness and the “pursuit of beauty” sometimes overpower common sense and the desire to save.

Algorithm of actions

The first task is to dismantle the standard elements, leaving only the metal base.

Attaching the acoustic shelf

After that:

• A drawing is drawn, markings are made on plywood or chipboard. The dimensions of the new surface are practically no different from the dimensions of the standard one. Chipboard sheet is thicker than plywood. If you were able to buy plywood or had it on hand, you can fold it in two or even three layers and glue it with wood glue. A shelf made of one layer of plywood may not be able to withstand the weight of the speakers and will crack. It turns out that the efforts were in vain, a mistake was made.
• The new part is cut out using a jigsaw. Its length may not correspond to the length of the one that was dismantled. You need to check this - try placing it on an iron base in the cabin. The original shelf is usually slightly larger in size due to the specific fixation. The new one should be one centimeter shorter in length. In order not to break the symmetry, shorten the board on both sides by 0.5 mm.
• Cut out holes for the speakers. Markings are applied, taking into account their future location. Don't rush to cut out the parts - if you make a mistake, you'll have to take new sheets of plywood or chipboard and start the whole job all over again.
• Holes for the speakers are cut in the metal base. Markings are made on the metal frame. They are cut using a grinder. This must be done carefully - there is a risk of sparks when the disk and surface interact. It is necessary to use personal protective equipment, such as goggles and gloves, a carpenter's coat or an apron. The car interior should be protected from accidental damage.
• Using an additional layer of plywood or chipboard, you can complicate the configuration of the acoustic shelf and achieve the effect of tilting the speakers in any direction. To do this, you need to draw a drawing of an additional part that will help create an angle. The outline should be transferred to a sheet of plywood or chipboard, cut out this element, glue it with wood glue to the inside of the main sheet, and additionally secure all parts with self-tapping screws.
• The edges are smoothed with a fine-section file and sanded. The resulting product can be coated with a wood primer and varnished so that the material does not deteriorate and lasts a long time. It can be negatively affected by high or low temperature in the car interior and air humidity.
• A cover is sewn from carpet. Carpet performs a thermal insulation function and reduces vibration. It is necessary for the salon to be beautiful and stylish. It will be difficult to guess that in fact the acoustic shelf is not purchased.
• The created structure is installed in the cabin and the speakers are connected.

We create acoustic podiums

It doesn’t seem logical to change the shelf, investing effort, time and money into good sounding music, leaving the standard VAZ 2114 podiums, which are made of plastic and eliminates more than half of your work. Plastic does not dampen the vibration of the speakers at all; on the contrary, it enhances it, creating rattling and extraneous noise. Therefore, we will make new podiums, tougher, and making all the previous torment justified.

For the new holder you will need:

1. Columns.
2. Installation rings (included in the kit).
3. Gloves and brush.
4. Epoxy glue and hardener.
5. Fiberglass and lycra.

If you start creating a podium from scratch, some skills in woodworking and other work with materials will come in handy, firstly, for an untrained person this is unrealistic, and secondly, people with such skills can imagine what exactly needs to be done without this article. Therefore, relying on the option that there are no such skills, as well as special equipment, on the basis of a standard podium we will carry out the procedure for strengthening it using the materials described above.

This procedure is done as follows:

1. We cut off the mesh (part of it) from the podium and fix the installation ring; the structure should come out monolithic and rigid.
2. We put lycra on the structure.
3. Mix glue and hardener.
4. We spread the resulting solution onto the lycra and, as in papier-mâché, glue the fiberglass (you need to stick 3-4 layers).
5. Let the structure dry.
6. We install.

The option of polyurethane foam is “not an option”: firstly, it causes corrosion of the body, and secondly, in addition to vibrations, foam also dampens sound.

Disadvantages of ovals or “pancakes”

What are the disadvantages of “pancakes”, which is why they are not used in good systems? The first drawback worth mentioning is the location, since these speakers are designed for shelf installation, they are always placed at the back. And the sound should come from the front. This is not an immutable rule, but music is always better perceived if it is heard from the front rather than from behind.

Because of this, by the way, it is impossible to listen to music normally if you have passengers sitting in the back. Because as soon as you turn up the volume control a little, they start complaining. This is not surprising, since the speakers are screaming right into their ears.

Also, “ovals” have all the disadvantages of coaxial acoustics. If a woofer, midrange, and tweeter are combined in one device, they will sound worse than component speakers due to design features, as well as the design and quality of the crossover.

Which Speakers to Put on the Rear Shelf

Which speakers put on the back shelf

First of all, you can go there and put any size you want, not just 13 like the tailgate.

Secondly, the sound is better than the door.

Thirdly, everything is easy to do; it is impossible to do Shumka rear doors.

And by the way, the quality of the Kicker coaxial inexpensive speakers was quite satisfactory. It was quite possible to save money on front speakers. Also, the coaxial, especially mine, doesn't benefit from the components, they sound decent.

The pancakes are mounted on the back shelf through podiums. The podium to the shelf was reinforced from the inside with screws, and the speakers were screwed to the podium using fasteners that came with the speakers. The holes in the rear shelf are made of mosaic. Later I glued a shelf with STP inside and an iron partition where the shelf was attached. I took the wiring from the rear speakers (which I unplugged), although I had to increase the length. Now I'm thinking about how to fill the void between the shelf and the metal. What about the experts who give advice? What material?

Lada 2114 Turtle › Logbook › DIY rear shelf.

To begin with, I walked around and looked around the shops. The shelves start at 1500 and go up. It won't work. The plywood turned up. There is a jigsaw. There is a warm garage. All conditions.

This is what you need to take off with.

To begin with, I started dismantling the original shelf and sides. But in the photo they are nothing. They look.

I unscrewed the screws, the sides are in no hurry to fall off. I thought. The sidewall will still go to waste. I solved the problem with a jigsaw.

Machine without shelf. Nothing too.

I left the sides alone for a while. Shelf for long-term storage.

I decided to make the shelf in two parts of different widths. To make it easier to open. Cut it out and screwed the hinges on.

What has happened so far.

Further refinement with a file. Things slowly came to a close.

To begin with, I “carpeted” the turtle.

The most difficult part is the sides. I tightened it and screwed the speaker on.

Upholstered and installed a shelf. What happened in the end?

I think it's good. All that remains is to carefully stick the register in the trunk and buy some adhesive tape to secure the shelf. She already fits well, but that’s for sure.

I threw in the wiring, soldered it, connected it, listened. The rear does not outplay the front, but only complements it. This makes me happy. But we need to change our heads.

What surprised me: the rear license plate began to rattle. With the trunk closed, you can only hear it when standing behind you, but with it open... it almost shouts over the music. Or is the ShVI bad or are the speakers good? You'll need to put something under it.

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.

Solution option

Explanation

Completely dismantle the sides and shelf

Nothing will make noise in this situation, but you will deprive yourself of space to install an audio system. You can forget about high-quality sound inside the car

Purchase a ready-made podium for durable material with holes for speakers

A good option that requires certain financial costs. All you have to do is install it in place. Disadvantage - it is not always possible to find a shelf that is ideal for all parameters

Make a podium with your own hands

This option provides minimal financial costs and the opportunity to create a shelf that will meet your smallest requirements. The downside is that you have to do the work yourself, which not everyone can handle.

Choosing the right speakers for your car based on different criteria

The first rule of high-quality sound is the number of speakers in the car. But this does not mean that you need to place three dozen sound sources in the car - everything should be in moderation

It is important to respect the presence of different frequencies. For example, you can use one or two subwoofers, two tweeters and seven or nine midrange elements

The number of sound sources in the car should not exceed reasonable limits. For example, an 11.2 sound system (eleven regular speakers and two subwoofers) is considered the most functional for an ordinary car. Often one subwoofer is enough, and high power is not necessary. You should also comply with the following criteria for purchasing speakers for your car:

• absence of incomprehensible discrepancies in frequencies, a large number of high-frequency devices;
• correctness of the kit - it is better to buy ready-made audio systems than to create them yourself;
• the presence of either two powerful speakers with low frequencies or a subwoofer;
• the ability to connect the entire system to a small car amplifier;
• reasonable power consumption so as not to drain the battery from one track;
• the presence of built-in fuses in each sound source or correct connection.

It often turns out that the speaker buyer is not very knowledgeable about electronics, but undertakes to install the purchased devices himself

In this case, you need to pay special attention to the type of connection. Each speaker or entire sound system must be fused

This will help avoid unpleasant overloads.

Therefore, it is better to immediately take advantage of the offer of ready-made audio systems with fuses in each sound source. Such a purchase will allow you to simply connect new sound sources and get high-quality sound. With the help of ready-made systems, you can change the sound quality in your car within a few minutes.

How to choose acoustics for a car

In the design of such speakers there is actually... more than one! The playback range is divided into areas - each “subordinated” to its own dynamics. Special filters are used as signal “splitters” (they are also called crossovers), and then each speaker has its own. Serious models have a crossover in a separate housing, but simpler models make do with a capacitor (the simplest filter) on the speaker housing.

The advantage of coaxials is their large coverage of the reproduced frequency band. The main location is the standard seats of the car. Usually they are equipped with standard equipment. This type is suitable for car enthusiasts who are not picky about car sound and need an inexpensive solution. They are suitable as a replacement for old speakers in a car when maximum simplicity is needed. I took it off and installed new ones.

They come in different sizes: 13 and 16.5 cm. The larger the speaker area, the cleaner and louder the sound.

Made with my own hands

Bottom view of a raised shelf with installed speakers.
Installation is simple, there is nothing complicated - I ran the wires and cut holes in the shelf. Then I installed and secured the speakers and connected the wiring. The wires are very thin, so I bought and used others with a larger cross-section. He led them along the right side of the car, under the carpet underneath, then out into the trunk. In Kalina this is not difficult to do, and quickly.

The sound has become much better and more pleasant compared to how it was before with factory music. The kit includes wires, screws, and some mounting angles that I didn’t even need. Everything is neatly packed in a cardboard box.
