e39 BM54 lost front right channel

3 posts in this topic

Noticed last night that I wasn't getting any sound from the drivers door speakers in my 2003 530i.

 

Is this likely to be the amp (mine is a bm54 that must have been replaced under warranty at some point as it has a 2006 build date?). Reading around it seems that the whole channel (ie front and rear on same side) fails rather than a single speaker? or is that just bad wording?

 

Does anyone know the pinouts for the plug on the bm54 so that I can test continuity of the front right speaker? 

 

Are there any other likely failure points?

All my left channels went on my bm54 I sent it to baris at Carphonics Enfield he sorted the issue out, seems it's a common problem for them to go down, he can also do few other upgrades on the bm54 as well check them out
