adcom 5300

HI I have two adcom 5300 amps in great shape. I just bought a Sony STR dH 810 multi channel receiver, my other receiver died. I have all the video set up on the Sony and it works great, but when I tried to hook the the two Adcoms up to the receiver, I don't get any sound. I want to run my CD player here but it won't work. The reason I have the Ad coms is that I have 8 sets of KEF speakers through my home which I want to run with my cd. So I have the speakers into switches and then into the Adcom 5300 they are then run banna plugs into the Sony and then I hook my cd player via plugs to the Sony. No Sound. Does it have the power to run my amps, do you know a way to run it or should I look for a separate adcom receiver to just run my stereo system and the leave the AV off.
