When the car is playing music, there is loud knocking in the back speakers and physically pops. The back of the vehicle where the speakers make a loud knock and has been mistaken as another car hitting you. The knocking can be heard at low volume level and is ridiculous at high levels. The vehicle had the issue when new and the car still is. It might be more than just music. The problems exist when stationary and moving at all speeds.
