I am about to pull the trigger on a new A4. The dealer has almost the exact model I want except for color and the B&O sound system. It also has the black optic package which I am not thrilled with because of the 19" rims. I drove an A4 with the B&O system and one without and I could certainly hear the difference. I asked if it could be dealer installed and they said they didn't think so. Does anyone have any experience with this? I have a custom system in my Acura RSX and I'm not sure I can go back to a stock sound system. Especially since I am used to my Boston Acoustics which are awesome.

 

I think your are best to find a car with it installed. It would be many thousands of dollars to do a conversion if it could be done at all.
