I apologize if this has been answered - I tried finding old posts and and couldn't find anything to answer my issue. I have an 01 with the stock audio system, which I've been happy with. However, I noticed that my rear speakers mostly stopped working recently - I say mostly because with the fade full rear and the balance full left, I get a little bit of high, tinny sound.
For a while I had a lot of crap in my trunk, so I'm wondering if something knocked the feedback amp - is this a possibility? I'm not seeing any broken wires, so I think that drops it to the amp, the speakers, the feedback unit, or less likely the head unit (which otherwise works I fine).
I'm trying to avoid replacing the head unit, but would be fine testing speakers, the amp, etc. if I had any guidance. Any ideas what to look for or test?
Thanks again for all the help!
