Whining sound.

Hi hope you can help, got a focus 12 plate. When I start the car I hear a whining sound through my radio even raving, what is the cause and what is the fix. Cheers

does the whining sound change in note in line with engine speed?

Do you only hear it with the radio on?

Is there a female in the passenger seat? 

That was the root cause of the whining in my focus; gets worse the faster I drive. Main reason I've fitted an passenger airbag deactivation switch 😉

Could be a bad contact on an earth cable causes electrical noise.

Yeah the sound is on only when the radio is on but the engine is off.

Lol no female passenger
