Speaker pop
 

When i go over bumps or pot holes the back speakers pop like theres a short, radio or speakers. Any help will be appreciated.

Thanks

IMHO, the speakers & audio are the worst problem with BMW, especially since these are considered high end vehicles - you might have some blown speakers, I know my 2001 came with some when I bought it used - or a bare wire somewhere, but I'm not the expert on this - is your X5 stock? DSP?

Chances are your rear speakers are blown. I had my rear speakers go out after the first year and a half of ownership. After the second time it occurred, I just swapped them out with MB Quart components. I couldn't have been happier since.
