Are you serious? For about the same price, you could pick up an MTX Thunder 6000, that would blast the living crap out of that Xplode. The only thing that the Xplode has going for it, is it's color scheme is pretty. Other than that, it's a terrible speaker.
Yeah, sony makes some great products but car audio is just not their thing. I suggest Rockford Fosgate subs, Alpines are good too. check out www.crutchfield.com
