Why not add two more channels?
Your tranny is plenty big enough, and your heatsink has enough room for atleast four chips, maybe more.
It would not cost much to add two more channels.
Just a thought.

Why do you not use the RC filter in the inputs?

The schematic is very well...

Thaks for schematics and the replys.

The RC's purpose is mainly to block out DC. I feel extremely uncomfortable without a resistor to ground after the capacitor. Corner frequency is calculated to be at around 0.72Hz.

I have no need for more than 2 channels. This amp is mainly for my stereo setup. My HT's using commercial amps. Don't wanna risk something blowing halfway thru the show...
