I just bought my M3, the previous owner had installed a componet set in the front, but the tweeter and mid-range speaker are not working. He has the front componet set and the rear speakers wired into one 2channel amp. There are two wiring harnesses in the back that are not hooked up to anything... I'm new to BMW's please give me some advice, or tell me where I can find some wiring diagrams...
Thanks
The Bentley manual has wiring diagrams of the stock stero systems. You can also go to www.unofficialbmw.com
They may not be of much help if the previous owner has rearranged the wiring. The current setup is a bad deal.
