Hisssss from my speakers.

[harleyqn]

Hey all I've started to notice an annoying hiss from my speakers. it's always there there at a constant volume. Obviously I can drown it out by turning up the radio, but once I've hit the mute button, the hiss is back.

I've only had my new passat for 2 days, and it's optioned with the Dynaudio system.

It seems to me that something isn't grounded properly?? Additionally the hiss/white noise is still there once I've turned off the car, turned off the radio and even pulled out the key!!

I've even locked the car waited 10 mins and got back in and it's still hissing.

Any opinions and advice? I think I'm going to have to take it back to the dealer... I'm also concerned that something is still connected and there is a constant drain on my battery.

Are these amped??

is there RCA's running form the back of the headunit ?

I get that, even outside the car. But its normally from a big night out and its in my ears...

but seriously. its odd even when the cars off... how loud?

Not very loud, but if I sit in the car with windows up I can hear it. If I'm standing outside with the front doors wide open and put my ear 3 inches from the tweeter, I can easily hear the hiss. Interestingly it doesn't hiss from any other speakers only the tweeters!

They are amped, however it's the factory fitted Dynaudio system. You'd think it shouldn't hiss... I have a feeling that some part of the circuit isn't grounded properly or come loose and introducing background noise into the system/tweeters. I'm also wondering if this has happened to anybody else?

Its either noise being induced in the RCA's, crossovers or tweeter itself, its easy to have a play around to find which it is, but because your car is new, youd void warrenty, defs go back tell them about it, should be a easy fix,

Hey Harleyqn,
I had a hissing like sound which came from the tweeter/speaker in the drivers side rear passenger door(The speaker next to the door handle) To me it sounded like a geiger counter going off, refer to this clip but skip to 2.00mins to hear the sound i'm talking about. http://www.youtube.com/watch?v=TCqsnap6a1A. Same like yours, the offending noise only came from the one speaker.
It bugged the crap out of me, but was gone in 2 days and hasn't come back, so i never got VW to look at it.
Hopefully yours rights itself, otherwise take it in to VW to get it looked at.
Cheers,
Jayse.
