Hi All,
Throwing out the help flag. Recently my rear driver-side door speaker developed a buzz. Roughly a week later both rear door speakers went out, followed by the fronts. I still have sound from the front center dash speaker and some from the pillar speakers. The sub still works as well.

The dealer can't figure out what's wrong. They've had it for two days now. Hoping a amp swap will be the cause. They're trying that tomorrow.

Anyone else run into this? Thoughts? Ideas? They pumped white noise through all the speakers sucessfully, it just doesn't reach the door speakers any other time. Very odd.

2011 Q5 S-line with the B&O stereo.

Thanks!
