I took out my system and my nitrous and now I guess I might as well sell this box I built. It fits under the rear seat, I used some large nuts under the seat brackets to lift the seat like an inch for more clearance, you can have them if you buy it. It used to have 2 12's but I took one out and cut the box so I could put the bottle in it, I guess you could put a new top on that side and re-carpet it if you want. Ill take some more pics of it tomorrow, its out of the truck now.
Id like to get $100 for it, I live in Bluffton, SC- about 40 minutes from Savannah, GA
