OK, I have a very odd audio system problem in my car. It seems that the mid/high speakers (dash and deck) do not function on the left side. They are working fine on the right.

The diver door sub/bass speaker *does* work though. Now... here is my dilema.

I've looked over the wiring diagrams on in the 300+ page PDF and found the pages for the '92 audio systems. I found two systems but the wiring on neither would explain what/how my system works. I could understand the operation of the door mounted bass if I had the 5 speaker (per side) system running off of the two amps (one for each side).

However I can only locate three speakers (dash, deck, door). I pulled the panels and I found the tuner module (that is interfaced with the head unit viat the 10-lead round cable) and two units that look like the amps for left and ride side (according to the wiring diagram).

If one of the amps was dead I'd understand no left side audio but I still have the bass. If I fade the head to full right the door base speaker quiets to near zero output. If I fade to full left I only have the door speaker working.

When I used the concole fader (fore/aft) to fade, on a left-rear there is no discernable audio (there is some channel bleed into the right side but basically no audio). Fade to left-front and I get just the door speaker.

Looking at the only diagram that shows the seperate amps left/right I should have 5 speakers (1 dash, 1 door and three drivers somewhere aft.. I'm not fiding them). Regardless.. the diagram indicates that the door/dash are driving off of similar output leads, so why is only the bass working?

This making no sense to me (and by now probably not making much sense to anyone reading this). I don't know what other methods I can use to try to narrow down the problem.

I'd like to get an IPOD installed at some point, and maybe it's the head unit that's not working right? If I have an aftermarket head installed, are there any that will play nice with the factory components in the rear (using line-out, with an adaptor to power the factory amps etc?) or will I need to re-wire the entire system, get more amps and some crossoves to make the door drivers and dash/deck drives work right?

HELP!

I used to do this for a living... but this system has my stumped...

If pictures of the parts are helpful to illustrate anything.. I can pull the panels again and take some pics.

PS. I have no clue what model Becker head unit this is but it does have the changer output, I know, I pulled the non-functional changer out, and pluged the head's cable right into the rear tuner/amp last week).
