Hey Guys, I have a Rotel RMB-1075 and RB-1070. With the RB-1070 being 130 watts for the two channels and the RMB-1075 being 120 by 5. Should I be using the 1070 for my fronts or just use them for my back surround speakers. I am thinking of using the 1070 for the fronts for a bit more power, not much I know. Thanks in advance.
