Splitting audio channels

[johndo18]

I currently own an Adcom GFA-555 to power my 3.1tl's. I am in the process of building a surround sound system. I was looking into getting another Adcom, something like the GFA-2535 which would produce 200 watts to the center channel and 60 to each surround. My other option would be to get another GFA-555 and run 1 channel to the center and split the other channel for the surrounds. That would put about 100 watts to the rear and 200 to the center. My question is is there any problem with splitting a channel like that. Or should i go with a deticated channels. I have 2 options right now and i dont know which route to take. Any advice Tom

You cannot split the amplifier channels, each speaker in a suround system needs it's own descrete apmplifier. It doesn't matter if you use monoblocks, 2 channel, or multichanel, as long as each channel has it's own amp.
