I picked up 6 Crown Commtech amps from work this summer! Each of the amps actually has 2 amps, which are bridgeable. I bridged 3 of the amps for my center and surround speakers. I used 2 of the remaing in unbriged mode and biamped ny mains. The Remaining amp, a commtech 800, I'm going to bridge and use for a sub when I find the right non amplified sub! This gives me 7 discrete amps.
