Almost embarassed to ask some of these questions!!:D I have been looking at a lot of amps. Looking to run maybe just the center channel (rti12) off of an amp. Still planning on the onkyo 803 or hk 645 (Just missed out on one tonight on ebay) So with either of these I was thinking that they would have plenty of power to run the remaining speakers if I ran an amp to the center. Have been looking at mostly just two channel amps (parasound & adcom) Now here's where I get lost. Can I use just one channel on these and will all 200 watts go through the one channel or do both channels have to be running at 100 wpc? Also, the amp is the power to the speakers alone right? (Not added to the receivers power to the same speaker?) Sorry for the rookie questions!
