My Avic-Z1 isn't outputting a full signal out of the front right RCA output to my amp. The speaker is just barely audible with tons of static type noise. When I switch the amp input cables front to rear, the noise goes to the rear speaker and the front sounds fine, so it's definitely not the amp. What's funny is after I switch the cables around, it starts working normally for a day or so. Then it starts sounding bad again.

 

I just moved my Z1 from my car to my new F250 pickup about a month ago. I just got new amps, so I'm wondering if the amp is loading the outputs too much or something. The amp is an Alpine MRV-F345.

 

Anybody ever heard of this issue? What does Pioneer charge to fix something like this?
