I've been sporting a 12" ported Alpine type R in the rear of the WK for a while now, taking up lots of room and cant really put anything in front of it. My amp, due to the previous owner, was located under the driver seat with wires run underneath the frame of the seat. I had to clean it up. So I ordered:
Cerwin Vega Stroker 1000.1 amp
2 Rockford fosgate 12" Prime stage 3 P3SD4-12 shallow subs DVC
kicker 2 way power distro block using maxi fuses
and tsunami ground
wired with 0 gauge wire because it was free from a car in a junk yard
and kicker shielded speaker wire
I used 3/4 MDF and outdoor/indoor carpet from lowes.. the color doesnt match, i know this and will correct it when the black I ordered finally comes in.
I had to do it this week or never do it for 6 months because my wife works 3rd shift and the saws would wake the sleeping bear.
First, I tore the huge useless plastic floor out. Cut the bottom of the box and measured everything else. The top of the box is .75 bigger on the left and right sides to set on top of the edge... which turned out not to matter.
The dimensions are 43"x24"x4.75 giving me about 1.8 cu ft. the subs only need .6 ea. So we're good. I kept them close together so a suitcase or anything else could fit in that spot. The grills for the subs are hard steel.
Once i put the box in place, i mounted the amp on top of some .75 and .5 MDF blocks to keep the amp off bare metal. One of the feet actually serve to keep the box from sliding back. the seats keep it from sliding forward. It also allows the air under the amp to move. the amp also has a built in fan pulling air from passenger side and blowing to driver side.
The cargo cover, the smallest lower step, is built to simply sit on top of the recess lip of where the old false floor was. I stepped the cargo cover down from the box rather than sloping as others have. It is more functional that you can set groceries and what not on the lower level and not have to worry about them sliding all over the place.
