Solution

1. Preparation

Gather tools: screwdriver set, multimeter, wire strippers, and electrical tape.
Ensure the vehicle is in a safe and well-lit area.
Disconnect the battery to avoid electrical shocks (negative terminal first).

2. Inspect Speaker Connections

Remove the door panels (if applicable) using a trim removal tool to access the speakers.
Check the speaker wires for any signs of fraying or disconnection.
Reconnect any loose wires and secure them with electrical tape if necessary.

3. Check Wiring Harness

Follow the wiring harness from the amplifier to the speakers.
Use a multimeter to test for continuity and check for any shorts to ground.
Repair or replace damaged sections of the wiring harness as needed.

4. Test Audio System Components

Reconnect the battery (positive terminal first) and power on the vehicle.
Test each speaker individually to determine if the popping sound persists.
If the issue continues, consider replacing the amplifier or head unit as necessary.

5. Final Assembly

Reinstall any door panels or components that were removed during inspection.
Ensure all screws and fasteners are tightened to avoid rattling or vibrations.
