• Biannual Dust Cleaning: The subwoofer amplifier acts as a heatsink. Use compressed air to clean the internal cooling fins. Dust causes thermal shutdown.

• Capacitor Forming: If you live in a humid climate, the manual suggests powering on the system for 2 hours every 3 months to reform electrolytic capacitors.

1. Swap the speaker channels: Swap the speaker channels to isolate the issue. For example, if you're experiencing issues with the front left speaker, swap it with the front right speaker.
2. Check the speaker wires: Inspect the speaker wires for damage or wear. If damaged, replace the wires or repair them using wire strippers.
