I went up to Ovation, the one of the local audio shops, to get a dash kit for my *new* car, and my buddy Bill was doing a demo of a 13w7. They use a 500/1 to power their demo subs so they don't blow the lower-end subs with a 1000/1, and he turned it up really loud to show the guy that a w7 can really slam, and it just died. Amp clipping > your soul. The guy still bought two 13w7's, and two 1000/1's. I was amazed. The reasoning was that 500 watts will blow it, but 1000 won't, and I guess its kinda right. Two pairs of boston Z's and two 300/2's also went into his little BMW, rich bastard.
