Sound System Option

Ins_328 · 03-20-2019, 06:51 PM

Just purchased 2011 328. I saw some posts in here that if you have tweeters on the door and no central dash then you have option 676, if there is central speaker it's 677. So the thing is I do have a central dash speaker, but vin says that my car equipped with 676. So where is true?

In the F chassis type the 676 option has a center speaker .
As far as I know that only started in the F chassis not the
E chassis. e9x no center speaker as far as I know.
Fxx series has center speaker not sure when it started.

Also have a look at the amp in the Driver side wheel well.
The 676 amp is way smaller than the 677 amp and has no
fiber optic line feeding it.
