Solution

1. Preparation

Gather tools: multimeter, flathead screwdriver, socket set, and OBD-II scanner.
Ensure the vehicle is parked in a safe location and the ignition is off.

2. Inspect Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the cover and identify the fuse for the audio system.
Use a fuse puller to remove the fuse and visually inspect it. Replace if blown with the same amperage.

3. Check Wiring Connections

Remove the head unit using a flathead screwdriver to gently pry it out.
Inspect the wiring harness for any loose or disconnected wires.
Ensure all connections are secure and free of corrosion. Reconnect as necessary.

4. Test Speakers

Disconnect the speakers from the head unit.
Use a multimeter set to the ohm setting to measure the resistance of each speaker.
A reading of 4 to 8 ohms indicates a functioning speaker. Replace any defective speakers as needed.

5. Reset Audio System

If applicable, consult the owner's manual for the reset procedure for the audio system.
Typically, this may involve pressing and holding specific buttons on the head unit for a set duration.
