Heres the interior, nothing special really:
Here is my dash, just painted all of the trim when we replainted the truck to kind of accent the interior a little more:
Here is my custom made fiberglass box, it has a Thin Mount Pioneer Premier 12" 1200 watt subwoofer behind the passenger seat, powered by a Rockford Fosgate 1200 watt 2-channel amp mounted behind the drivers seat. The reason i used fiberglass was to be different of course, because noone really has them where i live, plus i didn't want to sacrifice seating comfort for sound performace:
All work was done by me. It probably took me atleast 6 months to complete the box, due to lack of time and patience, but it was all worth it in the long run.
