I have an Apline MRA-F350 5 channel amp. Ive had it for about a year and it worked perfectly fine. However, while I was driving today it just shut off. All the lights are on along with a red light. I read tha manual and this is what it says.

Lights Red:

Protection circuit activated due to excessive voltage or current, shutting down system.

Solution:

Ensure correct voltage is applied before continuing use.

or

Ensure correct current is applied before continuing use.

Anybody know what I should do from here?

By the way, it only shuts off when I turn up the volume on my HU. When it plays quietly it works fine.
Thanks

Check your ground. Be sure there are no shorts in any of the other wires.

Found the problem, the pos. and neg. on the left rear speaker were shorting out
