Interference audible through tweeters

Hi guys
Ive got a problem with my 1.9 dci Laguna II, basically noise is coming through the car speakers, namely the tweeters. It is heard as a buzzing when the engine is running, when i turn on the lights it becomes louder, when i accelerate the volume changes. When the interior light fades out you can also hear this happen as a sort of whine noise.

Can anyone help me with this, it isn't the radio or the speakers, and the car is completely standard i.e no amps etc etc.

It is driving me mad, and only happens once the stereo is turned on, and happens whatever the volume is set at, however you can hear it more at say Vol 0.

Hi Andy,

Sounds to me like electrical interference coming from your alternator, its quite common particularly on older cars. Not heard of it on the Laguna II though.

What you will probably need to do is get a noise supressor fitted, not sure where though. But a good ICE company will be able to advise and do this for you.

Hope this helps.
