BMW X5 stereo help

[Jamesvm]

Please can someone help me!! I’m fairly confident my X5 has a sub in it which I think is much needed but looking in the storage locker with the fuses I’ve found this plug. Now I think it went to a sub but it’s only 5 pins? All the ones I can see for sale all seem to have a completely different connector to then that don’t look like they’ll fit? Has anyone seen a sub connector like this before? And if so do you know which brand of sub it fits? Cheers, James

Welcome James

You are correct that is where BMW sat their DSP (digital sound processor) 

Take a look at www.realoem.com put the last 7 digits of your Vin number in the search box it will call up the parts list for your model so you should be able to find the part numbers you need to look for. I am not sure but I do recall some one on another site built his own sub and mounted it there, there is also a company Cartronix that repair and upgrade the BM54 units.

You can also check out www.newtis.info for information on retrofit and wiring diagrams, both sites are BMW and used by Dealers.

Good luck
