The subwoofer is a low-frequency speaker, which in most cases is installed in a special box and is mounted in the boot of a car. The location of the subwoofer does not matter because the human hearing is arranged in such a way that it does not distinguish between the location of the low-frequency sound source.
In order to achieve deep and clean bass, the size and shape of the low-frequency dynamics correlating shall be pre-calculated. For the 10-inch dynamic, you need 20-25 liters, 12 inches-25-35 liters, 15 inches-and 60-90 liters. The 15-inch speakers typically use only the sound pressure competition.
Calculating the shape and dimensions of a sabufer's box is better in a special program. The best way to put a car in the boot of a car is a truncated pyramid. The back wall must have an angle of 23 degrees, which is the angle of the back seat back angle. If you have a small trunk in your car, you can do a "stelsbox" for a saboofus: it will be a narrow hulle that needs to be placed in the rear of the car. If necessary, it is possible to cut the floor slightly and lower the corp below into the niche for the spare wheel.
If there is a suitable low-frequency dynamics, the subwoofer's writ can be made with its own hands. The material will require a thick plywood, glue, and a cardboard (soundproofing material).
