I just bought the yamaha 5790 reciever. It has two settings. 6 or 8 ohm. If I was to buy the Epic 60 500 system. Which settings would I use. I see the 60's are 8, but the other speakers are 6. I don't think each channel is selectable so which do I use? And since these speakers are different ohm specs, will this cause the reciever to run hot?

Thanks
