Automotive subwoofers on the market is presented the greatest set - for every taste and wallet. But with the apparent wealth of choice, it is not sometimes possible to find a subwoofer, which is most suitable for your car. It is often quite often a non-standard subwoofer in the car in order to maintain the maximum possible useful volume of the trunk. In this case, the subwoofer has to be assembled independently.
1
The most suitable material for the manufacture of the subwoofer body is moisture-resistant plywood. It is easily processing and is not susceptible to bundle from temperature drops. It is also permissible to manufacture the body of the chipboard (chipboard). True, the body from the chipboard is very difficult and working with it is not very convenient. MDF slab has been perfectly proven, but working with this material requires serious skills. Yes, and the product ultimately turns out at all cheap.

Before the start of the manufacturing process, it is necessary to produce an acoustic calculation, whose techniques in sufficient quantities are laid out on the network. Do not be afraid, it is very simple. The calculation will allow you to accurately establish the necessary geometric sizes of the subwoofer case, most precisely responsible for the task.

Based on the calculated data, choose a low-frequency speaker. A lot of models are presented on the market, but it is better to choose from proven brands. Gorgeous low-frequency speakers make JBL, Infinity, Dynaudio, DLS.

Using the data obtained by calculation, cut the wall of the case. In one of the walls, cut the hole under the low-frequency speaker. Do not forget to prepare a hole for switching terminals. The place of their installation is selected, depending on the planned point of the subwoofer in the trunk. We produce a subwoofer body assembly. Common self-tapping screws are used. The distance between the fastener points withstand in the range of 5-7 centimeters. Do not forget to provide internal ribbins. They are necessary to prevent unwanted vibrations leading to the distortion of sound.
5
All the joints of the hull panels carefully process the sealant on both sides. We produce processing moisture protection impregnation and paint the case. Inside the finished body, it is necessary to glue with vibration insulating material or handle with a mastic with similar properties. Excellent vibration insulating materials produces STP, widely represented in our market. On top of the vibration insulation we stick a sound-absorbing material of the type of foam rubber or synthetic procession, a thickness of at least 20 mm. We install a low-frequency speaker in the housing, without forgetting to connect the mounting wires to the terminals. Speakers are installed necessarily through a foam gasket. The assembly is completed.
Let's hope that these brief recommendations will help you make a car subwoofer with your own hands. Good luck on the roads!
