Well now that I know that I may just go with a 4 channel amp and amp them all...thanks for the info. Now for right now I am still going to have the Pioneers in the rear, they only handle 40 watts rms...so say if I had an amp that put out 100 watts a channel I could just adjust a little under half for those channels and it'd be fine? So this means I can get an amp with any RMS power rating at or above what I want and just adjust the level down right? I'm to all of this amplifier stuff.
EDIT: Is it critical to get an amp that actually pushes the full rms value of the speakers? Like will 100 watts RMS be a lot different than 150 watts RMS. I ask because as for 4 channel amps I can only go to about 100 Watts in my price range.
