Im trying to put together a system for my truck, but the problem is where to put the subs and what kind of subs to get. I drive a dodge 1500 quad cab. I dont want to sacrifice much back seat space (maybe 1 or 2 on the bench), but I would like people to know I'm coming down the road. I'm also in the military so Im on kind of a fixed budget (about $800-$900 for the whole system). Any advice would be greatly apreciated.
