[QUOTE="keep_hope_alive, post: 8616651, member: 576029"] if you have a slight short in the speaker wires it can cause the amp to fade out then come back. Even one wire strand shorting out (usually at a speaker or crossover connection). While it would normally go into protect, it's possible the short is slight enough it isn't going into protect but reacting similar. To test if this is the case, you can isolate connections by removing one speaker wire pair at a time and see if the results are replicated. Of course, measuring voltage at the amp is important as a loose ground can cause this also. If you measure lower voltage at the amp terminals, the ground may be compromised. Ring terminal to bare metal, properly torqued, etc. will fail over time due to oxidation and vibration. [/QUOTE]
