I've had a ten inch sub in my 2005 Access Cab for a while now and I wouldnt think about going back to just four speakers. However, I would like to reclaim the footspace for the rear passengers so I was wondering if any other access cab owners would like to brainstorm a bit and figure out the best way to go about it. I already have the amps mounted to the back wall behind the seats. If you want details, just ask, but sufficed to say it sounds like I did a lot worse damage than it turned out. I'm guessing most of the other access cab owners wouldn't go to the extremes that I did.
Here is my initial idea for what I want. Raise the back seats up on a three or four inch mdf box that goes down into the storage compartments. This would give room for the bottom of a sub woofer and your passengers would have even more room to stretch out. Carpet the box and viola, no one knows you hid a sub, and possibly an amp on the other side, under those seats.
Let me know if you guys think of anything.
