first Xplod=crap. I like sony's home products a good deal but their car stuff just doesn't cut it.
second I'm running 2 12" MTX Thunder 8500's. I like em, but I got em from my buddy that sold me the car so if I was puttin in my own sub choice I'd probably end up with something else.
and definitely try to stay away from just about anything best buy/circuit city is givin u
