Mikey Posted March 20, 2008 Share Posted March 20, 2008 I have an intermittent problem with the rear door-mounted speakers on my 300Tdi. They recently stopped working so I removed the (non standard) CD unit and checked the wiring, everything seemed OK, but the speakers were still not working, however they started working again a short time later. After a few days the speakers stopped working again. This time I removed the rear speaker unit to check the wiring, that seems OK, but the speakers are still not working. I was wondering if there are any other wiring connections somewhere in the bodywork that may have come loose. Quote Link to comment Share on other sites More sharing options...

I can't give you an answer I'm afraid, but I will be VERY interested in this thread as I have the same problem and have never managed to get them working again.

teabag Posted March 20, 2008 Share Posted March 20, 2008 There are three circuits to the rear sub. 12+v amp power taken from the head unit supply, (light green/orange wire at the amp, also a local earth wire which is black at the amp). The 12+v amp switching wire (purple/yellow at the amp). The audio signal cable (black & white wires in a screened cable). A break or lose connection in any wire will stop the sound. The colours may change but the circuits have not. Quote Link to comment Share on other sites More sharing options...
61a Posted March 23, 2008 Share Posted March 23, 2008 Good luck with your speakers Mikey. I have similar problem with the n/s door speaker (only got two doors) which has a habit of going on and off when you hit a pothole, and there of plenty of those around here at the moment !!!!! I have checked and cleaned all the connections but it still has a habit of going off. Then it will be fine for a while. My usual method is to give the dashboard a clout just above the radio and with a bit of luck it comes back on . I have tried replacing the radio connectors without luck and have decided either there is a problem in the unit itself (unlikely) and to buy a new one or to rewire the speakers when I have a free day . The joy of a Disco ! Jules Quote Link to comment Share on other sites More sharing options...
