If it is behind or under a seat, make sure you leave enough slack to allow some movement. At the resonance frequency, the meter will read the lowest result (sealed enclosure) or the highest result (ported and bandpass enclosures). Two enclosure types that are the most practical for most cars are the sealed box and the vented box. The reasoning behind many people doing the second battery is a silly one. Remove all wood shavings before you go on to the next part.

Clearly sound is basically nothing more that the vibration of the air that is based on something moving. This will help to prevent variations in speaker tolerances and input power from restricting system output. The ground wire needs to be attached to the vehicle chassis and it should be kept as short as possible. Once you have the speaker and port openings are cut, you need to put some silicone sealant on the tip of your index finger and reach all the way into the enclosure to seal the inside joints of the baffle board. This enclosure offers excellent damping, good power-handling, and it is very easy to build. The volume of a cylinder is pi*r2*h, or (3.

Mounting the Amplifier


Now that all of the harder work is done, we are on to the easier part. Mounting isnt much, but I have offered some tips that may help.

1. First of all you will want to choose where you want to mount the amplifier. Choose an area that has plenty of ventilation to prevent the amplifier from overheating. Some places you may like are the trunk, on the back of the rear seat, under the front seats or attached to the subwoofer box.

2. Before drilling any holes, carefully check the area underneath the vehicle where the amplifier will be mounted to make sure it will not interfere with wires, brake lines, fuel lines, the fuel tank or any other objects that could be damaged.

3. Using the shortest screws possible, mount the amplifier how the manual from the manufacturer tells you to.

Tip 1: To avoid drilling into your vehicle, place a board that is slightly larger than the amplifier underneath the carpet where you want to mount the amplifier. Then put the amplifier over the board and drill in the screws to mount it. The board will provide a sturdy foundation and prevent you from drilling unnecessary holes into your vehicle

Tip 2: In vehicles that dont have a trunk, mounting the amplifier to the back of the back seat is a good place to start. Check the seat movement and determine how the cables will connect to the amplifier before mounting it though.

Tip 3: If you decide to mount the amplifier under a seat, you have to check to make sure it has the proper height and depth between the floor and the seat.
