Yeh, I was thinking of one of the three amps. Use my MRX as a pre pro. The MRX has enough for the surrounds, but I want to use one of the three amps and connect the front L/C/R speakers to this.
Just thought it would be more clear, more juice not alot but enough to get me that I won't be clipping the MRX. my MRX goes from -75 to +15db. I am about +5db on the dial. I am thinking if I had a 300w per channel amp hooked up to the MRX I may have to turn the dial now to about say -20db on the dial.

Anthem MRX520
M5HPv4
VP160HPv4
