Thanks for the replies. To clarify I do not have a seperate amplifier to run these two speakers and I hope I dont have to buy one to get these two speakers working. The speakers are on an outside patio and I would like to be able to listen to them at the same time someone is using the Denon to listen to something else. I have the system set up as 5.1 and I have no intention of using the 7.1 feature. I was told that I could assign the back surrounds to a second zone but I am only on my third lesson of latin and they say I need at least 427 more lessons to understand the manual.
