right now i have 1 18" BTL in and want to put a second one in but space is somewhat limited and i dont really want to give up my back seat sooooo i was wondering if i could just wall it? how would i calculate size (cubic feet) and how would i go about tuning since with a wall you pretty much tune the cab instead of the box? any ideas from you experienced builders?
