Ok, I'm a newbie and I'm not sure if my amp is shutting itself off or what is going on. When I am listening to my speakers at reasonably high volumes the sound shuts off and then all that I receive is static unless I let the receiver sit for 10-15 minutes. I tried doing searches and looking in my manual but have not received any help. I'm not sure if I have something hooked up incorrectly. I bought a used Denon 3300 and I would think that it should be able be reasonably loud without it shutting off as it says its wattage is 105. I get the static no matter what I try to listen to it in although sometime regular stereo puts out some music. It has happened every time that I have tried to turn up my subwoofer. Also, I have most of the things hooked up with generic RCA plugs as I have yet to get to the store and buy some good ones so I'm not sure if that is the problem.
