Never used one, but I would buy one now.

Bought this for a video/audio system for a RV I was working on and wow. The amp pumps out the power for the Polk Audio db651. I liked the blue lights on it. The amp was nice and heavy, and when an amp feels like that, for the most part thats a good sigh of a good amp. Didn't run it long, so it got only a little warm, but with A/B amps they get warm to hot. I don't think he's going to have a problem like that. Great product though.
