i know there has been threads, but i'm not quite sure if this is what i'm getting on my car.

the past 2 wks, i've heard a hizzing .......... sounds as if there's a bee buzzing.......on the front passenger speakers.

i don't know if i've blown my tweeters or my 6 1/2's?!

can someone shed some light on this for me pls, it's driving me bonkers!!!

thx in advance!

yes, i know you can get some feedback when you're on the cell.........but i hear this buzzing/rattling sound when i'm not on the cell.

i will have to check if any of the gromets holding the speaker in has come loose. do i just pop out the speaker cover or am i gonna have to take out the whole door panel to get to tighten the speaker gromets?!

Hi guys,

I have an '03 M3 with the same problem. There are actually two service bulletins out about this.

One is the passenger side door speaker buzz and the second is buzzing/rattling of the rear deck (where subs sit.)

If you take your car in, just ask them to check these two service bullentins. They should be able to look it up and fix it no problem.

The more complex audio issue I'm having is, when driving listening to the radio, sound is being cut off to certain speakers than comes back or shifts to other speakers. I have the HK upgrade.

Anyone have or hear of this problem?

Hope that helps,
where exactly did you get these "service bulletins?! would come in handy when bringing it in for repair.
