Radio sound dead

[genphreak]

When you say older amp, if you mean one that came from a car with M20/M30 and Hi-Fi sound, I am sure you cannot!

If you mean one from an M50/M60 car with Hi-Fi sound, I think yes.

Scored this from a 94 540 today:



Is different but the connections appear to be the same.

Well the new old one kinda works if you play with the fine pin connection. Wont work loose and wont work connected, somewhere in the middle I get rear and right and left but not all together. Used Gordons Stabilant 22 and no change. Put the old amp back in and still works. Son is thinking the solder connections to the small pins are compromised on the one we just scored. At least we can see that compared to the old one. If no deal I can return and score more free stuff lol.

I have a 1994 E34 530i with trunk mounted CD changer and I get no audio. It's intermittent. But all channels cut in and out at once so I don't suspect power amplifier. Is there a source for schematic diagram of this?

Those diagrams show interconnections between the radio and the rest of the car but not the innards of the radio itself.
