I tried to keep the interior as close to the original as possible. I stripped out everything and put dynamat on all the doors, side panels, floor, ceiling, and trunk to cut down on some noise. I also put in a kenwood stereo. Two 6 inch, 120 watt speakers in the doors, 2 6x8 240 watt speakers on the back deck, a kenwood head, and 1200 watt alpine amp for my subs, and 2 12 inch coustic subs in a kicker cabinet. While it sounds like a lot, with the windows down, and the exhaust system (straight pipe with glass pack and resonator) the stereo is just enough to hear over the sound of the car.I had the seats reupholstered, all new vinyl through the car, and new carpet. Everything else is original.
