I have an 08 Sierra extended cab, and needless to say there isn't much room for subs. I am interested in a single 8 (1508 likely) in a .75 net ported box tuned to high 30's on 1000 watts (behind center console in center of floorboard), or 2 10's like SSA Dcons or DC Lvl 2's on the same power in .5 net each sealed box (subthump under seat box)

Any thoughts on what'd have more output, and/or sound "better". Looking for other ideas that I can run that are American made and don't cost a fortune.

I mostly listen to rock, but want to be able to crank it up occasionally to show up some friends or just get my bass fix.
