Hi, I bought lately the RTi70 and the PSW202 for my home system. Now for the center i ve got a Klipsch sc-1 and for my back speakers i ve got the Infinitys alpha 40. And for the last i bought the Denon 1803 as a receiver. Now every time i put the sound up in a movie my Denon clips(stops). My Denon is a 80watt-7 channel. Is my Receiver not strong enough for my Polk or for what i want to do with it?????????
