Strange sound on 2008 X5 4.8

on monday when walking up to my car I hit my alarm/door locks to unlock and then hit the auotmatic rear hatch release to raise the rear hatch. Coming out of the passenger side rear speaker located in the back pillar at full volume was constant static. Only this speaker. So loud you could not get near it or sit in the car. I started the car, changed audio source, turned off audio all togther, and the sound did not turn off. I then turned off the car, reset alarm and then unlocked the doors/turned off alarm and the speaker noise stayed on the whole time.

Finally set the car alarm and a locked the doors, waited until the alarm cycled on about 30 seconds. Sounds was on this whole time then finally sound stopped when i hit the door lock alarm off button.

Like I said very strange. There was a slight electric burning smell in the rear hatch area when this was over. very slight and has since gone away. Any ideas or suggestions?

You described a similar problem I had with my 4.8is. It turned out to be a bad amplifier, without the burning smell. Part number is 65-12-6-940-977. Hope that helps.
