Help with Alpine pdx-4.1 amp issue


2013-05-18 2:04 pm
I bought a car that has this installed. The issue here is that it is set up to drive two small subwoofers and one of the outputs from the amp is not working. I have switched the subwoofers to confirm it is not the speakers and did the same with the wiring. It is definitely one of the outputs from the amp

The two fuses on the am are fine also.

Here is the manual for the unit.

Any ideas on what could be wrong and is it worth fixing?

Thank you
