I'm thinking of buying 2 model 200 amps. to power my 2 fronts (POLK RTI50). My question is can anyone tell me if I can hook them up with my SONY RECEIVER 4ES? The 4es has a pre outs for fronts, center, rear, etc. I don't want to buy them if they are not compatible. I'm new with separates. Also, if it does work if I want to listen to 2 channel music I know that the amps will power the fronts but if I want to watch movies in surround will the amps and the receiver work simultaneously so that I can get a 6.1 effects? I'm sorry if this is a stupid question but if anyone can educate me on this matter I really appreciate it. Thanks nicodim55
