Hey everyone, the car did not come with an amplifier so I currently have no sound. So I am in the market for one. Problem is, I do not know which one to look for. I thought I had logic7 system due to having equalizer and surround settings on the iDrive and also a center speaker on the dash. Then I read about the Divac system with the door speakers having a silver trim/bezel and beige/brown color speaker, which I have. So I decided to give the dealership a call to see if they could look it up for me. The guy gave me a part number for the amp (65127845163) which is the individual amplifier. However the guy had a "hunch" and was "pretty" sure which doesn't comfort me. Is there any other way to confirm which amp I need?
