Solution

1. Preparation

Gather tools: Multimeter, screwdriver set, wire strippers, and electrical tape.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the audio system fuse using a fuse puller or pliers.
Inspect the fuse for any visible breakage. Replace with a new fuse of the same amperage if blown.

3. Inspect Wiring Connections

Remove the head unit from the dashboard by unscrewing the mounting screws.
Check for secure connections at the back of the head unit, ensuring all wiring harnesses are fully engaged.
Inspect speaker connections in the doors and rear deck. Look for any frayed or disconnected wires.

4. Test Speaker Functionality

Using a multimeter, set it to the resistance (ohms) setting.
Disconnect the speakers and measure the resistance across the terminals. They should typically read between 4 to 8 ohms.
If a speaker reads 'infinite' or '0' ohms, it may need to be replaced.

5. Reassemble and Reconnect

After all repairs and checks, reconnect any wiring that was disconnected.
Reinsert the head unit into the dashboard, securing it with screws.
Reconnect the negative battery terminal.
