No, no -- he means 75x4 channels (4 ohms) PLUS 300 for the subwoofer (fifth) channel. It's also a true hybrid design, like the high-end Alpines of a couple of years ago.

I've heard great things about this amp, but is it *really* smaller than what you're using now? The pictures of the MB make it look pretty massive.

Anyway, there's one on eBay now...used, and already getting a lot of bidding going. Might be a way to pick one up for a deal...
