I want to add an amp to my 7.1 setup. My question is that I have Klipsch Reference speakers all the way around and they do not have the same wattage ratings. Fronts-RF-3II- rated at 150W max continuous, 600W peak Center-RC-3II- rated at 150W max continuous, 400W peak Surrounds(L,R)-rated at 110W max continuous, 300W peak Surrounds(back)-rated at 150W max continuous, 400W peak I am looking to add an amp either a single 7 channel B&K 7270, or a 5-channel, with a seperate 2-channel to power the surround back speakers. The problem is that I am planning to add an amp that would supply 200 watts to each channel, but wouldn't that exceed the speakers ratings, and cause damage to the speakers in the long run? What wattage rating should I be looking at? The rooom it is going into is very large. How else could I go about this? Thanks in advance for the help. BTW, I am going to use my Onkyo 898 as the pre-amp.
