! have a 98 ford 350 club wagon that runs and with a wall in it that holds six 15's. The box is four inches thick and it is sealed from the back. The box is 28 cubes and it is tuned to 40hz, it has all thread for bracing. The van has two 5.25's and two 6 1/2's on the ceiling and 6x9's in the doors. The doors and roof is reinforced. This van was build for Mod class, I was doing 60's with about 9000 watts, the front area has all the panels, seats, dash and seat belts in tact. must see to appreciate. I need $4000
