Strange amp on/off problem

[skatingrocker17 10+ year member]

In my Durango I have two amps and two batteries. The battery under the hood is connected to a battery in the back that powers a sub amp and an amp for my mids/highs. The mid/high amp is the one I'm having trouble with. It's a Kenwood eXcelon KAC-X542, it ALWAYS power on with the car, but sound doesn't always come out. When I turn just the battery on it always works but when I start the car the amp turns on but sound USUALLY doesn't come out. Sometimes it does but usually it doesn't. The sub amp always works. I used to have a Sony amp for the mids/highs hooked up to the exact same power/ground/remote/speakers and it always worked. Could it be an issue with the amp?

Yes. I would call Kenwood and send it in for warranty repair. If not, grab a new amp. Or try it in someone elses car and see if it is in fact your cars problem.
