I am new to car audio and have 2 Kicker CRV 12"s subs and and a matching amp, and everything else. I'm ready to build an enclosure, but don't know anything about enclosure design/theory. The basic requirements for the enclosures are that they have to be slanted slightly on the front side and pretty small (roughly 1ft^3) so they'll be sealed. I don't really want to get into the specific on measurements of my truck (unless necessary) my big question is: for best bass, should I build one box for both, or two boxes, one for for each? I have quite a bit of space across the back of my truck from side to side, but the space from the back wall to the seat is the limiting factor.
