Grounding a car radio is an important task that should be done when the car is new or when it has been in a crash. It helps to keep the radio working and prevents it from going out. To do this, you will need to remove the battery and plug it into an outlet. Then, you will need to remove the cover on the back of the radio. You will then need to take off the screws that hold the antenna in place. Once these are gone, you will need to take off the top of the radio. Now, you will need to cut a hole in one end of the antenna and fit it into the hole on top of the radio. Then, fit another antenna into this other end and screw it in place. Finally, put back together your Radio and enjoy your music!
