Get a bunch of T Amps for $20 each, and some 13.8 volt power supplies for another $20 each.

I have a good friend who sold an ATI monster 5 channel amp and replaced it with a Parasound Halo monster 5 channel amp. The parasound runs hot. He misses the ATI. You may want to check out their amps if you want something that will sag your floor and have the capacity to output more watts than you'll ever use.

Enjoy the Music. Trust your ears. Laugh at Folks Who Claim to Know it All.
