4 8 0. Usually the low frequency that comes with the system improves a little, but it will happen at the expense of power handling. As the speaker moves forward it goes 0 degrees through one quarter of its cycle to 90 degrees. If you are planning on adding on additional amplifiers in the future it may be a good idea to choose a larger power wire now rather than later so that it will be able to handle the increase in power.

Installation I have decided to list the steps in point form so that they will be easier to follow. You can often hear the bumpin sounds of the latest hip hop and club tunes blasting from random cars, and you realize that you would love to have those sounds in your own car. Decide upon a point in the firewall to run the power wire through to the inside of the vehicle. 0 It's very important for me to explain to you that any recommendation won't take into account the volume that will be displaced by the drivers, crossovers, internal braces, and, in the case of a vented system, the port. Carefully put the two pieces together and secure them by using screws or nails.

Plan #1 - Sealed Subwoofer Enclosure
WinISD recommends a 1.55 cubic foot box for our sealed enclosure. We'll achieve this by using 3/4 " MDF for the enclosure with external dimensions of 15.5" x 24 " x 10 ". This will be a simple rectangular box. Modeling the enclosure we see that it has a 87 dB sensitivity and a -3dB (half power) frequency of 42 Hz. This box should give very strong output when it is combined with the 12dB/octave boost provided by most automobiles.

SPL (1W/1m) - 87 dB
-3dB @ 42 Hz
Here is the layout of our subwoofer enclosure. We will need to cut the following pieces:
SIDE QUANTITY DIMENSION
TOP/BOTTOM 2 24" x 10"
FRONT/BACK 2 24" x 15.5"
SIDES 2 15.5" x 10"
JL Audio 10W1 - 1.55 cubic ft
Plan #2 - Vented Subwoofer Enclosure
WinISD recommends a 3.2 cubic foot box with a 24 Hz tuning frequency for our vented enclosure. Using a four inch port we'll need a vent that is fifteen inches long. We must take this volume into account. The volume of a cylinder is pi*r2*h, or (3.14)*(2)2*15 = 188 cubic inches. Divide this by 1,728 to get cubic feet and we add 0.11 cubic feet to the enclosure.
We'll achieve this by using 3/4 " MDF for the enclosure with external dimensions of 19.5" x 30" x 12.5". This will be a simple rectangular box. Modeling the enclosure we see that it has a 87 dB sensitivity and a -3dB (half power) frequency of 24 Hz (the tuning frequency). This box should give incredible amounts of output when it is combined with the 12dB/octave boost provided by most automobiles. This is to be expected with a box this large. In practice we would probably make the enclosure half this size, or similar to the size of the sealed enclosure.

Here is the layout of our subwoofer enclosure. We will need to cut the following pieces:
SIDE QUANTITY DIMENSION
TOP/BOTTOM 2 30.5" x 12.5"
FRONT/BACK 2 30.5" x 19.5"
SIDES 2 19.5" x 12.5"
