Question type: Maintenance & Repair

My hyundai sonata 2011 started bringing akward
sounds while playing any music track or even
radio by whistling with a loud noise that makes
music drop low and whistles in a noisy way .. Is it
the stereo wiring issues ? Or The IC power ? Or
something else  .. Im helpless

The sound comes from the ignition system on your engine. May need new spark plugs & wires, also ground connections are crucial.

No man im talking about the car sound system . Speakers stereo and so . You went way too far on this one


So does it make the noise with the car off? I bet not.


All I was saying is the ignition system of the car can cause interference threw the stereo which then is amplified threw the speakers. Just pointing out a cause for that weird sound coming threw your speakers.
