TERRIBLE! PLEASE HELP AUDIO PROBLEM
 

So I jump started my bmw from the front hood area one day and the speakers started making this fuzzy loud sound, it hasn't gone away I thought it was maybe a fuse but the side door speakers make the loud fuzzy sound and so does the one in the trunk but the little speakers on the dash work and project the music just fine! DID I BLOW THE SPEAKERS AND HAVE TO REPLACE?! Please help me!

Hmmz without hearing the exact noise it's making I'm guessing this happens with the engine on? It could be a bad ground or your alternator which has ground related issues.
It's called ground looping but I'm just taking a shot in the dark here without hearing it or gaining more info.

Better not to jump start a X. Better to charge the battery up and start it up on the car battery. You can cause an electrical spike when you use another car to jump start the X and with all the electrical components on a X they can be damage by the spike.

It's just the speakers I tested all other buttons for any abnormalities and they work just fine, it's just the speakers they make a loud noise that sounds like when your searching for a radio channel and it's all distorted but then they go quite and go silent and make a quick zap sound intermittently, also my radio module located in the trunk has to be replace because it wasn't working before anything with the speakers! Could it be that?

I would have to hear it , never answered my question though does it do it with the engine off? As far as the radio it's a possibility but do you have a cd player or whatever and still does it? Then maybe not..

When you jumped it may be either a resistor/regulator popped in the alternator but you would would have other issues. Maybe knocked the ground wire loose or something?

Do you have a DSP sound system?

Mine itermitedly does this when outside tempuratures are over 15'C, engine running or not
I have dsp and my sunroof drain flap was stucka and flooded the trunk, had to replace radio module and i noticed water was on the gps dvd reader and dsp amplifier

Its the amp

It does it with the engine off or on I do have a CD player but it doesn't work the only speakers that work are the dash tweeters, well I have absolutely no other problems in the car
