Actually S676A is Hifi rather than top Hifi. Yes I have a 2010 X5d and 335d. Was S676A the standard offering after 2010? Base is S645A below.

No tweeters, bass is actually not too bad. The problem with S645a is the output is an attempt to equalize the signal due to not having tweeters. It is not a clean low level signal. It outputs direct from the head unit as high level. Does not have the amp in the rear quarter.This can be remedied by changing the VO/FA in NCS expert and adding the appropriate audio equipment of your choice. So, stay away from S645A, agreed that S676A is acceptable..
