Why do some vehicles have noise and electric current noise?
Because the Music player is connected to the car power supply A and the audio system is connected to power supply B, the voltage is different, but the ground wire is the same;
And the AUX audio cable connects the Music player to the car audio system, causing power supply A and power supply B to be connected to each other, causing current to flow through, which can cause noise!
