How does the radio work in a car?
How does a car radio work? The operation of a radio starts from the power supply and ends in the output of sound by the speakers. A radio pulls power from the alternator which is supplied by the battery. A wiring system is established to connect the alternator to the radio and the radio to the speakers.
What to do when your car radio stops working?
A loose wire somewhere will mean that the radio will not be working at all. You will need to check for this connection when your radio is dead. The best way to identify if the wiring has problems is using a voltage meter. Start with testing the ground wire (black), accessory wire (red) and constant (yellow).

Why does the radio go off when the engine is running?
Sometimes you might hear winning white noise that come and disappear when you turn your radio on especially when the engine is running. This is the alternator winning that is normally caused by a bad ground to the head unit or the speakers.
With the car radio on, open and shut each door firmly. If the radio cuts in, or out, suspect a crimped wire. Open each door and look for the thick rubber boot that goes between the door and the car. Move the boot back and forth, and see if the radio cuts in or out. If possible, peel the boot back and physically examine the wires.

What can cause a car stereo to only work sometimes?
