Here we have a good used fully functioning harman becker active sound amplifier removed from a 2015 M4 with only 41000 miles, this should fit all 15-19 M4/M3 F80 cars and maybe others with the same part number. It will come exactly as shown in the photos. Im also parting out the rest of the car, so If you need anything please send an email so I can list it on ebay for you. The car was damaged in the right side area.
