BMW Repair: BMW SPEAKERS, speaker wires, bme

Question
I have an 86 bme 325es, I have recently applied the anti- theft code, the radio comes on but no sound comes out of the speakers.  Is ther possibly an amp that has a bad fuse or am I overlooking something else.  Your knowledge will be much appreciated.

Answer
There maybe an amp in the trunk,no fuses that I know of for the amp.If you have a battery(D battery works well)you can check to see if the speakers do work.Take and touch the battery leads on to the speaker.It will make a popping sound if all is correct.Speaker wires are yellow and blues.
