What causes car radio to stop working?
Blown Fuse: One of the most common reasons for a car radio to stop working is a blown fuse. If the radio itself will not turn on, chances are good that there’s one or more blown fuses causing the problem. A damaged antenna means that your radio isn’t able to receive signal from stations.

What fuses are for the radio?
Most low-powered radios can use a 20-amp fuse without any issues. However, for high-powered stereos — those that produce 100 watts of power or more — you may have to use a 25- or 30-amp fuse. You may be able to use a wire clasp or harness already under the dash to secure the wiring from the radio to the fuse box.
How can I test my car speakers without a radio?
Remove the wires from the audio system, and with them still attached to the speaker, attach them to a 9-volt battery. You may hear a popping sound coming from the speaker. This means the speaker is working. If there is no sound, that indicates the speaker is blown.
How can you tell if your car stereo has been blown?
A multimeter tester helps you figure out if the cone or voice coil is damaged.

A multi-meter reading of 1.0 ohms means the speaker is not blown, but a reading of infinite ohms means it is blown.
