After playing my system too loud, my auto-protect feature on my amp initiated. Ever since then I am not able to turn up the subs very much before the auto-protect turns on again. The fact that everything works lessens my worries, but I am not sure what might have happened. If anyone has any ideas, please share. Just ask for more details if you need them. Thanks.
Check your gain/level setting on the amp. If it is set too high, it'll shut down. If you operate the amp with incorrect gain/level setting, it will eventually break down.
CIA? Are they related to FBI? Just kidding. Before you repair anything, make sure your amp is worth 2x the repair cost, or else it's not worth fixing. Lower the gain/level setting and see if it still shuts down. If so, then it'll need fixing/replacing.
