I bought a 645 Ci from 2004, 90k miles, 2 previous lady owners and I love it. I drove from Scotland to London at 90mph on average, and did 27 mpg.

I need to update a few things such as
-changing back speakers
-add Bluetooth connexion
-remove the mobile phone craddle between the two front seats.

Any advice on how to do that? I already looked at Youtube but I am looking for a few websites for parts.

Are the rear speakers crackly at high volumes? If so it may be the Logic7 amp that's damaged, not the speakers. It's a well documented issue of water ingress in the boot caused by blocked drainage channels and some fkwit at BMW putting electrical equipment near them.

That is exactly the case. Only by putting the bass at zero it removes the cracking sound. I was told by someone that it might have been an overuse of high volume and bass but you might be perfectly right. How do I know it is the Logic7 amp ? or is it standard for this model ?
