I need an amp to power my Polk Audio RC6s in ceiling speakers in my bathroom. I have two of them and they each have both the left and right speaker in them. I was looking to get a two channel amp and have no idea what one to get. What are some good suggestions with out breaking the bank that can make these work great? I had looked at the Onkyo M-5010 2-Channel Amp but didn't know if I need to even go with something that big. Thanks for the help!
