Car Audio: Why does my car amp keep going into protection?

Question

My car amp keeps flickering on/off all of a sudden. It goes into protection and about every 5 seconds flickers on and get a quick bass response and shuts off. I've narrowed it down some. Hope anyone has an answer...

Car amp should be fine because I went out and bought a new one it worked for a little while now the new amp is doing the same thing.

Capacitor is wired correctly and is working. With or without it, car amp does the same.

Wiring is correct, ground is good. Like I said it just happened all of a sudden and I've been using my system for over a year.

Don't know about my head unit. My other speakers work fine with the whole problem going on, it's just my sub out. I have a Kenwood Excelon, it does overheat sometimes and shuts down but would it cause just problems for my subwoofer and amp?

Answer 1

if your deck is operating fine with the internal amp pushing the door speakers etc. then i would have to quess that the issue is in your sub setup....    test them or swap them with a known good sub and see if issue is there

Answer 2

You need to dis-connect the system and then re-enter the protection code.It seems as if part of the code has a malfunction.

Answer 3

I am having the same problem with my amp also, tho not nearly as bad as you are having. i also recently got a kenwood excelon deck and thats when the problem got much worse.  i had to turn my amp gain down from 3/4 from 1/3 on my old cd player and the bass boost from 15 out of 18 to 3 out of 18. its helped quire a bit but still does it if i crank the volume really high with the sub output level up high. also don't run  the sub woofer crossover setting on the deck above 100hz. hope this helps
