John, thanks for the 1987 BMW 325 stereo wiring information contribution!
For 1987 BMW 325 with an amplifier, you only have two speaker wires due to a common ground system. B+ is correct along with ground. Left positive front and rear is the yellow wire with a plug on it. Right positive is the blue wire with plug on it. Do not wire any negatives for speakers coming out of radio. Use rear outputs, Green and Purple, off of the radio (POSITIVES). Dont forget to use solid blue, B+ constant for power antenna, This should be two light brown wires. You could however separate these two for amp turn on and antenna. Hope this helps. John
Help guys, i got a 1987 BMW, just change battery and i have the radio code, can you tell me step by step, how to enter the code, the manual i got do not tell me. i already try enter the number with the key pad, in the pass i believe i turn the ignition to 1 or 2, the rest i do not remember. thank you.
Ayonio, if you do not have the radio unlock code, you would have to obtain it from your local BMW dealer. Hope this helps. Good luck.
