Built entirely by Enormis Audio. Just took out of a 2011 BMW 535. Used for less than 1 year. The system cost 4k when installed. Here's the breakdown:
-(1) custom built box for 2011 BMW 535 with port. Box also has orange LED lights that light up a BMW symbol as shown in picture.
-(1) Rockford Fosgate T500-1bd Constant Power
-(1) Rockford Fostgate 12 inch subwoofer T1d412
-(1) breaker switch
-(1) bass knob
Everything is in perfect working condition! Will not sell pieces separately!
