All the interior has gray carpet with billet acc. all through. I replaced the bench seat with buckets and made a center console to hold my Sony radio and EQ. Cut the back out to make a "walk-through" and I put 2 more buckets in the back.
As far as the sound system goes, I have Sony head unit and eq., 6 one inch tweetes and 6 six and a half midrange speakers throughout the cab and the back. I also built a wall from the top of my camper to the floor and filled it with four 12 inch Eclipse subs. To power all this I have a Rockford compassitor, & optima battery. I have 3 Eclipse amps. powering all the system.
