Hi all,

I own a 2010 330d lci m-sport with the base audio system, i am having huge trouble identifying the problems regarding my speakers not working correctly.

- The front left speaker/subwoofer is working perfectly
- The front right speaker/subwoofer are both not working
- The rear right speaker is also not working, it used to work sometimes when hitting bumps but eventually turns off and it stopped working at all now
- the rear left speaker is working fine.

I tried swapping out different speakers from working sides to sides that do not work and the speakers still have no output

I also bought a new subwoofer for the right side but still doesn't work, this is probably because the right subwoofer and speaker are connected in series.

I am at my wits end with this one

Any help would be appreciated guys

If you have a base system it's only the Head Unit and speakers.

In the base system the door and floor speakers are connected in parallel.
