I’m having some trouble with the speakers and audio system in my car. There is a buzzing noise before I even start the car. It seems like something is interfering with the sound system. I switched off the bluetooth from my phone and the car. Still, I hear the buzzing sound. If I turn up the volume on the radio, the buzzing gets louder. I want to be able to fix this myself. Can you advise me on what needs to be done?
