Future System

ill post some pics of my setup when i get a chance... if you are going to mount the sub behind the seat, 12" is a little too big. i used 2 10's in a box that fits behind the rear seat, and fires forward. for a 10" sub, in a sealed enclosure, you want between .75, and 1 cubic foot of volume. my box is roughly 1.8 cu/ft for 2 10's and really doesnt crowd the trunk too much. i mounted the amps on the back of the box (one pushes my subs, and the 6x9's on the package tray, and the other drives the 5 1/2 in the kick panels) as per your other post, dont drop the head liner!!! when you remove the kick panels, you will see where the factory run the wiring to the rear of the car... unless you have a big bundle of wiring, you can pull yours just like they did in dearborn...
