Why does my radio turn on but no sound?
If your car radio works but there is no sound from speakers, speaker wires that are grounded or clipped to a metal point or the speakers themselves are the most likely problem causing it. However, you may want to check a few other things before you proceed to fix this problem.

You should never panic in such a situation because you can solve these issues with a little technical know-how. In this post, we will take you through what you need to do when the car stereo works but there is no sound from the speakers.
Ensure The Wire Connectors of Your Speakers are Properly Installed
Check that the speaker wire connections are properly placed and inserted far enough into the speaker grounds to make good, consistent contact. Properly examine the speakers to ensure this. The speakers may be broken or malfunctioning if they still won’t play. If they continue playing, reconnect them to the system.
Check the Speakers
You should also do a visual check of the speakers. Examine components for any physical damages.
Check for a Blown Fuse
Like other electrical equipment, car radios are likely to include a fuse or two to protect them against power surges and other electrical hazards. In some situations, the excess current is discharged to the vehicle’s audio component, causing the fuse to burst and the circuit to be disconnected, preserving the radio.
Replacing a blown fuse will likely restore your radio’s functionality. However, if the new fuse blows soon after installation, you’ll need a trip to the mechanic’s shop. It indicates a problem with the electrical system as a whole, which can only be fully examined by a professional.
Check for Loose Wiring
Vibrations and bumps from driving on the road can cause the wiring on your radio to become loose. This includes the wiring of the head unit, amplifier wires, and the wires connecting the speakers to your car’s radio. Check all these wirings and make sure that none of them are loose. If you find loose wiring, fixing it may bring the sound back to your speakers.
Check for Faulty Tuner or Antenna
If you’re having problems with your radio rather than the CD player, the fault is most probably with your radio antenna.
If only the CD player is malfunctioning, the problem is most probably with your radio’s tuner. Therefore, before considering a DIY solution, you need to be clear on the situation you are facing.
