Maintenance Tips

• Ensure Ventilation: Install in a location with unobstructed airflow; avoid heat sources and heavy insulation.

• Secure Wiring & Connections: Use proper gauge wires, keep terminal screws tight, and connect the ground to clean metal chassis.

• Match Speaker Loads: Operate within recommended 2 Ω–4 Ω loads to prevent amplifier stress.

• Set Crossovers Correctly: Use built-in HP/LP crossovers to route signals properly to speakers and subwoofer.

• Protect from Moisture: Keep the amplifier dry; wipe away any condensation to avoid corrosion.

• Avoid Clipping: Maintain proper gain and input levels to prevent distortion and overheating.

• Monitor Status LEDs: The protect light indicates wiring, load, or thermal issues—check if it illuminates.

• Periodic Checkups: Inspect mounting, wiring, and cable routing every few months to ensure stability.

• Break-in & Usage: Gradually increase power during initial use to optimize performance and longevity.
