It will work fine as long as you split the stereo output from the preamp using "Y" cables or if your preamp has two sets of stereo outputs, use both pair. You will probably gain a little. But when a multi-channel amp is used as a stereo only amp, you gain some power due to the fact that the power supply only has to deal with two channels as opposed to many.
Bi-amping???????'s
I currently have a pair of b&w 605's with a Kenwood Km-z1 amplifier (6x115) and a Rotel 960ax pre-amp. I am in college and running on a tight budget. I was wondering if there would be any significant advantage to using 4 of my channels on my kenwood to power my 605's, as opposed to 2 (the B&W's have bi-wiring posts) If I were to do this would I simply split the outputs and run them into multiple channels on the amp? I have done some reading about bi-amping and it refers to adding additional cross-overs, ect..... Any info would be greatly appreciated.
Thanks,
Kyle
