Drivers side speakers no longer work
Hello all,
I have a 2016 M235xi with 102k on it. Today the driverside speakers crackled and then went out and have not come back. I want to troubleshoot this. All other speakers in the car work, so it is either the speakers, the wiring to the speakers, or the amp output to the speakers. One thread mentioned that it could be the idrive system, but that seems far-fetched. However, I will restart the idrive system to see if that is the issue. How does one troubleshoot this when everything is hooked up with harnesses? Can I test the output of the amp with a multimeter? Does anyone know where I can find a block diagram or circuit diagram that shows signal flow? I thought that maybe the components in the door were fed by a crossover, and perhaps that bit the dust. So should I start at the amp or the speaker? Any help would be great! Thanks. |

Is it just the front set of speakers that has issues or both the front and the rear speakers having issues? I would swap both front speakers to see if either or both work in their new location. I'm betting the amp is the problem.

I had this same issue with my left front recently.
Turns out the wire going through the metal inlet to the speaker got frayed. A splice had things up and running for me. |

It is just the front set of speakers. I'll swap them and see if they work in other locations. While doing that I should be able to see if the wires are frayed. Thanks for all the help! I will report back when I am done trying the suggestions.

I had a look, and the wiring looked good. I was stumped, so I decided to have a look in the trunk. I found water in the compartment with the amp. I have no idea how the water got there, but I got a new amp and will install it and see if that makes a difference. But first, I must find out how water got in my trunk!
