Weird AMP problem

[NLyle_]

Hey guys hows it going. Im having a problem with my subwoofers and its something ive never seen before. I have 2 sundown X-15 V.2 D2's on a 5000w BOSS amp and ever since it started getting hot outside, my whole system has been giving me problems. At first, when my car wasnt in a garage, it would take about a minute before my subwoofers would actually start playing like normal. This happened for about 2 or 3 weeks. But just the other day, I get in my car (its about 98 degrees outside) and they dont play at all. I open the back and look at my amp and the LEDS that are on the amp are coming on with the high hats of the song that is playing. I dont have time to dive into it during the week so I just let it be and hope that it fixes itself. What I did do was take my head unit out and look at the wiring behind it and accidentally unplugged the ground to it (my car was running) and it popped the fuse in the engine bay. So I reconnect the ground and replace the fuse and the radio plays fine. The amp is still doing the weird LED flashing but then I turned my regular bass up to have something to hear during the week but when I turned it up pretty loud, the subs would start hitting. If it was a really long bass note, it would be fine until the bass note stopped then my subs would turn off and wouldnt come back on until the next long bass note. Im here just asking for things to look for or what I should troubleshoot or anything that could possibly help me get rid of this problem. If yall need to know anything else about my setup or whatelse happened, please ask ill be happy to share. Thanks

Obviously the power amp has some sort of signal turn on detector circuit. Either you have changed its sensitivity somehow, or the sensitivity of the circuit has changed and caused the problem. The circuit also likely includes some type of LM timer circuit also. This would be set to keep the amp on for a certain length of time after an input signal reaches threshold to stop the amp cutting out in quieter passages. The timing of these types of circuits is set by an RC network attached to the LM timer chip. It is not uncommon for caps to wander in value over time and change the time delay of a circuit considerably. I would have thought that this would be particularly likely in a hot car environment.

Thanks for the reply. I'm going to be honest, I have no clue what any of those things that you mentioned are. I have a slight idea of what they could be but not 100%. So to clarify, you're saying that it is something in the amp itself that's making it do all sorts of weird things? If so, do you recommend that I get another amp to replace it or is it something else that I am looking for? Thanks
