Solution

1. Preparation

Gather tools:
- Multimeter
- Screwdriver set
- Panel removal tool
Disconnect the vehicle's battery to prevent electrical shorts.

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and locate the fuse for the audio system (refer to the fuse diagram).
Use a multimeter to check for continuity in the fuse.
If blown, replace it with a new fuse of the same amperage rating.

3. Inspect Wiring and Connections

Remove the head unit from the dashboard using a panel removal tool and screwdriver.
Check all wiring connections at the back of the head unit for any loose or damaged wires.
Secure all connections and ensure no wires are frayed or broken.

4. Test the Speakers

Disconnect the speakers from the wiring harness.
Connect each speaker directly to a portable audio source (such as a phone with an auxiliary cable).
Verify that the speakers produce sound. If they do not, they may need replacement.

5. Reassemble and Test

Reconnect all wiring and secure the head unit back in place.
Reconnect the vehicle battery.
Turn on the audio system and check if sound is restored.
