I have read around the forum that folks are using this amp and loving it in various games. I installed one in my Pin2k, along with upgraded speakers, and gotta say it sounds like crap. In order to get decent volume on the R/L I have to turn it up quite a bit. I have to keep the sub turned to like 5%, though, because anything above that and it's mud/distortion entirely. There is a lot of power coming out of this thing but it sounds horrible.

It came with a 5A power supply. I'm thinking this is probably the issue. I have seen a couple of posts here searching that say it really wants 6-8A. Why would they ship the thing with an inadequate power supply? Anyway, how are other people powering it? Is there a standard recommended power supply in a pin?

Could it be that this thing can't drive the subwoofer I have put in there? Honestly, this thing sounds like a massive downgrade from the stock system. So disappointing.
