Hi ive got a 1998 Ford Taurus and the trunks not to bad on it. I have 2 12" kicker L7's with a 3100 watt Legacy amp and an Audiobahn Eternal 2200 watt sub with a 2000 watt audiobahn amp. I want to build a box to make these subs shake windows and be as deep and powerful as possible. I can use the whole trunk. The dimensions of my trunk are about 41" wide x 15" tall x 36" deep. If anyone can help me out that would be great. Thanks, Jesse
