Speaker cable in the center console

  • Hello everyone, in the course of repairing the heater's vacuum regulator, I also wanted to tidy up the radio's tangle of cables. I am sure that all 8 speakers work even if only 4 pairs of wires are connected. But now I have found a second bundle of 8 cables with speaker plugs. Can anyone tell me what the second set is for or has it all been wired up wrong? Greetings Thilo

  • No offense, but what else is there to recognize? :wink: A lot has been patched together with grimp connectors, lustre terminals and Wagro terminals. The cables originally go to the amplifier next to the passenger seat. From there to the crossovers. Do you have a wiring diagram of the radio? If not, I have the one for an 85.

  • This gives you a bit of an idea of what it should look like. Hopefully your English is good enough.

    The way the wiring looks in your photos, the amplifier is no longer there. The black ISO plug with the cables goes directly to the loudspeakers.

    I'll have to look up the eight other cables in the wiring diagram. I only have a diagram for my GTS to hand at the moment, it's almost identical but not 100%.

    As Ludger says: check if the original amplifier is still next to the passenger seat.

  • Thank you very much, I'm starting to get an idea. Next to the passenger seat is just more patchwork. Where is the crossover located? I haven't found a wiring diagram for 86.5 yet. But I haven't had a close look at the link yet. Greetings Thilo

  • The crossovers are located in one set in the two doors and in the rear in the side panels by the bass speakers.

  • The sheer amount of cables is overwhelming ?:-(. Is it possible that a double cable set was installed for the amplifier in order to be able to connect different radios without any problems?

  • There is a standard wiring harness to the fade control on the driver's side, which is why there are so many cables.

  • Yes, I know that one, or that's not what I meant. All cables on the passenger side have been bridged (Sven's and mine) but there are still at least 8 cable lugs unconnected. Greetings Thilo

    Short answer: no. If you still have the M-codes for your car, then the radio, or rather which type was used, is also entered there. Otherwise it is as Ludger says above and you have the same Post....
