Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, screwdriver set, and possibly a wiring diagram for the audio system.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Check and Replace Fuses

Locate the fuse box for the audio system (usually under the dashboard or in the engine compartment).
Remove the relevant fuses using a fuse puller or pliers.
Inspect the fuses for continuity. Replace any blown fuses with the same amperage rating.

3. Inspect Power and Ground Connections

Reconnect the battery terminal.
Remove the head unit from the dashboard.
Check the power supply wires (usually red) for voltage using a multimeter.
Check the ground wire (usually black) for a solid connection to the chassis.

4. Test Speakers

Disconnect the speakers from the head unit.
Use a multimeter to check for continuity in each speaker. If any speaker shows no continuity, it may need to be replaced.

5. Reassemble and Test

Reconnect all wiring and components in the reverse order of disassembly.
Ensure all connections are secure and that no wires are pinched.
Reconnect the battery and test the audio system to confirm sound is restored.
