Sub feedback
 

I just installed (well paid someone to do it) a new BSW sub and the Stage 1 speakers. I am getting a problem with feedback from the sub only when the car is put into reverse. The X5 is a 2001 with NAV, DSP, Denson Ice Link and it has PDC if that matters.

Thanks,

Ron

I figured out what the feedback was from. It was from my LED backup lights. The bulbs would cause an error message for me to check the backup lights. Well I replaced the backup light bulbs today with some normal ones and what do you know, the feedback from the sub was gone! I am glad that I figured that one out. I would not have been able to figure it out except that BSW told me to recheck the grounding of the amp to the reverse circuit. That is what gave me the idea.

Glad to hear you got the issue resolved!
