lots of prefabbed boxes would work, or you can go to the forum section at
www.caraudio.com, sign up, and theres many really talented box builders on there that would gladly build you a box and ship it to you for a very decent price considering it can be as custom as you want.
yeah id say either buy a prefabbed box or make one to fit in the area you need it to.
Just buy some 3/4" MDF from homedepot. you can get more than youll need for around $30
Or you could just fold the seats down to fit anything lol
