Sluggo:

I have managed to shut my 7100 down only one time in about 2 years. I was driving it hard for over an hour and a half and it sits in a rather small space(only 3 1/2" above and glass doors in front so not a lot of air flow. It only made the right front channel stop so I would say that each channel has its own shut off. After I let it cool down it has performed flawlessly. Hope this helps smile
