If you’re ever driving in a car and the door rattles, there are a few things you can do to stop it. First, make sure the car has sound system that can play music. Second, try to keep your hands off the wheel while driving. Third, try not to open the door too much when you’re getting out of the car. Finally, if all of these measures don’t work and the door rattles from outside sources such as wind or rain, then you may need to replace your car’s speaker system.
