I've been looking at audiosource amps today. I noticed that the "Amp two" has a CD direct input. I know what that is, but here is my question..... If I have 3 of these amps hooked up, would I plug my CD player into only one amp? I'm assuming that if that is correct that I would plug it into the amp that is powering my main speakers? Would I be able to get sound from my CD player through the rest of my speakers?
