Nick, there are more discs coming out all the time with 7 channel music on them and for some reason many people like to listen to 7 channel stereo , which is what its called on my Yamaha. I am a purist and believe 2 channel is the correct way though I do use the sub to carry the bass. I have on occasion listened to 5 channel stereo and it does sound good but something tells me its just wrong LOL. Either the draw is more than the amp in the receiver can handle or its thermal shutdown. Shorted cables would cause it to shut down immediately.
