ext cab.

    what tuning? what amp? how big?

    so i was planning to put a DC audio XL 18 in my ext cab truck. but im tryna keep it as cheap as possible while still being a good system. i am now looking at a XL 15 instead. i know DC recommends 3.5 cu ft. now i want to have the box sitting in the back seat. it can go from the drivers side wall...
