EDIT: Thanks to you all, problem solved (see last post). I finally got 6 Athena B1's hooked up to my Onkyo SR502, and while giving it a test drive with Phantom of the Opera, the amp shut off and has a blinking light. Turned it back on and it played fine for a few minutes, then the music started to swell and off it goes again. I noticed earlier the left surround was a bit weak so cranked it up high, but don't know if this would cause the shut off. Any idea what I could have done wrong or what to do to try to fix this? This has really bummed me out.
