Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and wire connectors.
Disconnect the negative battery terminal to ensure safety when working with electrical components.

2. Checking Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use a fuse puller or pliers to remove the audio-related fuses (check the owner's manual for specific fuse locations).
Inspect the fuses visually or test with a multimeter. Replace any blown fuses with new ones of the same amperage.

3. Inspecting Connections

Remove the head unit from the dashboard (follow manufacturer’s instructions for disassembly).
Check wiring harness connections for loose or disconnected wires. Reconnect or repair as necessary.
Inspect speaker connections by removing door panels or accessing speaker locations. Ensure all connections are secure.

4. Testing the Head Unit

Reconnect the battery and the head unit temporarily.
Connect an external audio device via auxiliary input or USB.
Play audio from the external device to check if sound is produced from the speakers.

5. Professional Inspection

If sound is still absent after performing the above steps, it may indicate an issue with the head unit or amplifier.
Consider taking the vehicle to a professional technician for further inspection and potential replacement of the audio system components.
