For example, when your audio source device such as smartphone is connected to car charger on one side and playing music through an audio cable in the car on the other side. In this case, positive current enters your device through the charging cable, and some negative current will inevitably be transmitted back to the car through the audio cable, causing the car audio system to produce noise, affecting the music listening experience. **Q2 ** How to determine if noise is caused by ground loop. - ** ** Simply connect your phone to the car AUX interface using an audio cable and play music. If the noise disappears, it confirms that the noise is caused by ground loop.
