E36Propeller is an unknown quantity at this point
(Thread Starter)
I bought my 1998 E36 328i about 3 months ago, and it has the premium sound package(also known as the Harmon Kardon system). Well recently, my front speakers have been giving me a screetchy noise when vocals or high treble play. I usually play any tech music, so of couse I want clarity in my music, but now this is happening and I have to know what to do....1. get rid of the speakers and get new ones(aka they are blown)...OR 2. replace the capacitors as I have heard for the regular nokia system...OR 3. do i have to just tighten a few bolts...OR 4. get a damn new head unit?

I hope I'm not the only unfortunate sucker to have this happen, so if I'm not and anyone knows what to do, please help a fellow BMW owner out

Thanks for your time fellows- Joel

I have a solution, Do this at your own risk. You take either a rubber mallet or a 25lb. sledge, your choice (25lb. sledge recommended) you take a big back swing and aim straight for..........hmmm thats not the best idea, I don't know.

is it an in-dash cd-player? if it a trunk FM modulated one you can get weirdness. also, the comment about the wire's gone awry could be true too. but if a wire is not connected properly, or is touching something it shouldn't, i don't know why you would see a response only in the high-end. frequently wire crosses or improper grounded etc result in what is call a 60 cycle hum. that 60 cycle hum is a base noise not isolated to just the high end. try to find out if the screaching is isolated to a single speaker, or if it is systemic. that might help isolate your problem.

Black E36 M3 is an unknown quantity at this point
The upper freq. tend to go as do the lower when I speaker gets tired. If you can remove your door panel and remove the speakers and take a look they might be dry rotted. I know my tweeter and 4" were both bad in my M3. The 5 1/4 was still fin down in the kick panel, which is usually the case because it isn't exposed to the elements the others are in the doors.
I replaced mine but also added a aftermarket in dash CD player, 4 channel amp and JL Audio's 8" stealth boxes. I am a manager at a car audio shop where I live so I have to have good audio.
MB Quart makes a nice direct replacement and JL makes one that requires a little work.
Good luck...

that's the stanley murdoch principle: any job can be accomplished with the correct sized hammer.

also, in my 328is from '98...is that a HK speaker system and did alpine build the bmw stereo? someone put a crappy sony fm modulated 10 disc...i want to relpace it. should i go alpine head/in-dash or should i do the factory alpine 6 disc. the number of discs etc doesn't bother me. i would rather have quality. <_<
