Hi, I' trying to hook up my new 7100 amp to a Yamaha 5.1 receiver. No problems with the main 5 speakers - but here's where it gets tricky. I have two sets of speakers for which I have no pre-out for on my amp. They have been sitting idle until now. Since these speakers are outside and in my kitchen, they aren't the most important in terms of sound quality, etc. but they are inefficient and I'd like to drive them using the last two channels of the 7100 amp (using a speaker selector box, of course.)

My question is this: Can I use one of the "Y" RCA adaptors that split the signal into two between my Yamaha receiver and the 7100 amp without damaging the amp or worse, degrading the quality of the original signal that was supposed to go to one of the main 5 speakers at the amplifier? If this works, I'd be psyched because I don't have a Zone 2 output section on my amp and would love to find an easy way to get these extra speakers to run with good power and not jeopardize the main rooms' speakers. Any help or suggestions would be greatly appreciated!!!

Thanks,
Steve
