Installing new radio 1980

[mixybro4]

Attempting to put a new radio in my 1980 928. The old one is starting to fall apart. It looks like the previous owner had put a new one in back in the day because the wiring was very stupidly rigged. I have the radio working fine except for one speaker (the driver side door) is unaccounted for. I took off the door panel and everything is still there but the wiring is impossible to trace back. I see no amp, and there are four wires coming from the rear (red with white, red, brown with white, brown) that stop at the radio and are not going to anything, so I assume they went to the amp. I was just hoping if someone knows the ending location for the driver side door speaker wires because I cannot find them. Thanks

Hope this helps:

The speaker balance switch is located by the emergency brake. You should find the wires you need there.

When I installed my new JVC, I bypassed the fader control and let the radio do that function.

Is there a diagram that shows which color band goes to which speaker? Every two wires has a little band around it, all different colors

i'm pulling a lot of these audio wires out of the 84 - it seems stereos back then did not have front/rear faders - so on these cars the signal ran from the radio, possibly to an amp then over to a fader switch (by handbrake) - on this car I believe the amp was originally under a box between the pass. seat and pass. door - so the wires went from console to pass. door then back over to handbrake area then to speakers - you can catch all the speaker wires at 2 connections under carpet right in front of drivers seat - at least on this car you can and all this wire looks factory - weird system I found a separate radio tuner behind glove box - good luck

Ahh I got it. I just ran a signal through all the different wires till I found the right ones. Sounds pretty good! Almost done. Does anyone know if the relay under the dash serves and purpose besides pissing you off with it's buzzing?

What relay? the chime (buzzer on earlier cars) relay? (for doors, lights, seat belt...)

Radio (non-speaker) wiring:

Red/white - switched radio power
Red - permanent radio power
Brown - ground
White - antenna (& optionally amplifier) switch wire

The chime relay. I took it out. Got the radio in and everything. Will post a picture later
