[QUOTE="keep_hope_alive, post: 6866557, member: 576029"] seat belts are awful ground points. i don't like using them for a reduction in safety and increased resistance. monitor your battery voltage when the amp does this. if you don't know the voltage at the battery and at the amp, you don't really know what's going on. when you monitor amp voltage, monitor the amp terminals. this may be tricky while you're driving, but it should do the same thing when you're just idling in your driveway. go to an autoparts store and have your battery and alt load tested. both of them can fail. most likely, it's a low voltage problem. below 11V the amp will shut off. below 12V the amp will lose power.
