My car has bose system. So i haven't drove my car for 4 or 5 days, went and drive it today. the passanger side front speaker is making some weird noise, like i'm listening to radio but have no reception. you know how when you have no reception of the radio, they made some weird noise, so this is the noise that the speaker is making!

Only the passanger front speaker does it, and it can play my music just fine. i tried turning of the stereo, but the speaker is still making that noise. the noise is on and off, and the only way i can turn it of is to turn the car complete off which mean not on ON or ACC position!

can anybody tell me what my problem is? is my speaker blown, i tried playing the music loud and it doesnt sounded like it was blown. is the wires lose?? does anybody know what would cause this?

any help would be great!
thanks for reading!

Stop listening to weird music and all will be well!

It's hard to tell what it is without actually hearing it in person.

I'd lean towards a broken or loose speaker wire, that would not explain why it keeps making noise until the car is turned off.

Can you record the sound or describe it better? is the car under warranty still?

i'll try to record a video with sound tonight.
i was thinking it stopped making noise when the car is turned off because there is no power to it????????
oh....btw, i forgot to mention that i had a aftermarket sub and amp installed, the amp is only pushing the sub, not the speakers. and from what i know the guy who installed the amp and sub for me only tab the passanger rear speaker to get the source.
hope that'll help!

My bose setup sort of makes this extremely faint sound whenever the car is not completely off; I personally believe it is normal - just the design of the thing.

I don't know if the stock unit is the same - probably not. They don't differentially signal or have separate amps, right?

I figure the amps don't power down when the HU is off, only when the car is really off, and it is just the noise floor of the system with no signal supplied.

Ironically i vaguely remember that playing a silent CD track made it go away or be reduced, but I can so barely hear it with the engine off anyway - so that might no be accurate. I suppose if i really cared i would do a test with the car off, engine off in ACC with HU off, and engine off in ACC with silent CD.

But this is so far below road/wind/engine noise and I rarely use the stereo anyway (especially when parked).


OOPS almost forgot to post how this relates to your question.

I'd guess that the something about that door's HU<->amp<->speaker setup is messed up somehow; or it could be noise coming into the amp that it is faithfully reproducing.

I won't say any more than that at this time.

If you get your door open to look at it and have knowledge of the wiring, you should be able to logically figure out on which side of the system the fault lies.

yeah that speaker has it's own amp... I would bet that something is amiss between the headunit and that amp.. hard to say where.. take that door apart and if you can't see anything then remove the source wires and see if it still does it - if it stops then you know it's something with those - if it continues, then you know it's something with the power wires, or the amp itself.. keep playing and trying new things.. you'll narrow it down eventually

itz weird how now it doesn't do it anymore!
could it be cause i took off the mirror cover, and water got into the wires?

WikkedOne

LoL yeah water would do it... water just happens to be REALLY REALLY bad for electronics... I'm going to resist the chance to flame you right now.. but you should get that taken care of ASAP unless you like driving listening to music from your phone instead of your car.

c4125: ur radio is normal...it just occasionally receives other stronger radio freq... like ur cell phone or other. this is something we can blame fcc regulations on as i'm sure the radio can receive interferance but not give it.

try makin a cell phone call and place your cell phone directly in front of ur HU and see if that noise amplifies.

these things are common. you can even try it on some home desk top speakers with the power on and no music playing. it'll make erratic buzzing noises placed next to a cell phone searching for frequency.

as i said before, even i tried turning off the radio, the speaker and the only one speaker is still making the noise!
but now it seems to go away, so i'll leave it for now, just put the side mirror cover back on, hope it'll prevent doing it again!
