Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic socket set, and a screwdriver set.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Fuses

Locate the fuse box (usually under the dashboard or in the engine bay).
Remove the cover and identify the fuse related to the audio system (refer to the fuse diagram).
Use a multimeter to test each fuse; replace any blown fuses with the same amperage rating.

3. Check Wiring and Connections

Remove the head unit from the dashboard using appropriate tools.
Carefully inspect the wiring harness for loose connections, frayed wires, or corrosion.
Clean any corroded connectors with electrical contact cleaner and reattach securely.

4. Test the Head Unit

Reconnect the battery and power up the audio system.
If there is still no sound, use a multimeter to check for voltage at the power and ground wires of the head unit (should be around 12 volts).
If power is absent, trace the wiring back to the battery and check for breaks or issues.

5. Test Speakers

Disconnect the speaker wires from the head unit.
Using a multimeter, check the resistance on each speaker; it should typically read between 4-8 ohms.
If any speaker shows an open circuit (infinite resistance), replace that speaker.
