Wiring Issues
Loose or damaged wiring can also cause audio problems. Inspect the wiring connections at the back of the head unit and speakers. Look for any signs of fraying, corrosion, or disconnections. A loose connection can easily interrupt the audio signal.
Amplifier Problems
The amplifier boosts the audio signal to the speakers. A malfunctioning amplifier can result in no sound.
