The VAZ 2109 car from the factory does not have an audio shelf. That is why you have to do it yourself. A properly constructed shelf will contribute to the sound of your car speakers.
Instructions
Step 1
First, mark out the shelf template. As a template, you can take the decorative upholstery of the rear shelf. After that, you will need a ruler and tape measure. With their help, you can adjust the dimensions of the future acoustic shelf. Also immediately mark the holes for the speakers. You need to pay a lot of attention to template layout. This stage of work is practically the most difficult and responsible one. It is best to make the dimensions slightly larger than necessary. You can always cut off excess parts. Try to match the speaker holes perfectly.
Step 2
Try placing the shelf in its intended place. If necessary, trim off a few centimeters on each side. To work, you must have 2 sheets of plywood. The second sheet is cut in the image and likeness of the fitted first sheet. After that, you will need to glue them well. Spread the glue over the entire surface of both sheets. The result should be a monolithic board. Its thickness is usually 15 mm. Pay attention to the speakers. They can protrude strongly above the plane of the shelf. In any case, this will make it difficult to fit the shelf with a Carpet. To solve the problem, you will need another sheet of plywood. Saw it to fit the finished shelf. Make larger holes for the speakers.
Step 3
The shelf should fit snugly against the body. For this purpose, apply a dense, but at the same time deformable material on its lower side in certain places. It is recommended to use macroflex. Soak it in water in advance. After hardening, this material has good strength. You can cut it with a knife already in place.
Step 4
As a result, you should have a fitted shelf with speakers installed. It remains only to sheathe it with a carpet and mount it in place. Cut the carpet to the size and shape of the shelf. Add 5 cm to each edge. The fabric should be folded and attached to the ends of the shelf. U-shaped staples are usually used for fastening.
