when the cd player is on with the volume low and i acelerate it makes a wistling noise .when i accelerate more the noise gets louder but it doesnt happen when the cd player is off is this ment to happen?
Ok, you say the noise increases with engine revs. That means either the shielding that prevents electrical interference is faulty, or possibly you have the wrong plugs fitted. I would suggest you visit an auto-electrician
