Insert the fuse into the fuse holder and connect the fuse holder. It is an established fact that people tend to prefer the loudspeakers that they think are louder, as opposed to speakers that can handle bass levels etc. Now we have a complete new stereo system that is ready to go! Then put the amplifier over the board and drill in the screws to mount it. We'll achieve this by using 3/4 " MDF for the enclosure with external dimensions of 19. The resonance frequency is completely proportional to the cross-sectional area of the port, and inversely proportional to the length.

This is why we have coaxial and component speakers. 3 cubic ft SUMMARY Thanks to the ultimate rise of club music, people all over the place are desperate to create a club atmosphere everywhere they go. This is particularly true if you are driving an older model car. But I can say that it is worth checking out. In some cases the grille is secured from the bottom by screws, or by plastic studs which can break with excessive force. Connect the red plug on the RCA cable into the red plug (left) on the radio and the black plug (right) on the RCA cable to the black plug on the radio.

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"
