Hi all
So have the m3 on the road and have a few bits to do with it. First up is the stereo. It has the hardon kardon speakers (8 speakers) and amp in the boot the front speaker aren't working. There are 6 speakers not working in the front I took the passenger kick panel off this evening and removed the speaker, the speaker looks good it's Harman kardon speaker. I had two speakers in the garage so pluged one in place but still no good also tried the other one still no good so. There is a faint sound from the speakers when pluged in and crackling when turned up. I im thinking it's the amp thats the problem three speakers couldn't be faulty. Has anyone any experience with this. Anyone on here have a hardon kardon direct replacement amp from a bmw.
