Start over with the source unit volume at 75%. Turn the amplifier's input gain to minimum, then slowly turn it up clockwise until you hear slight distortion from the speakers. Back it down slightly for a clean signal. Ensure any built-in VU meter stays in the green zone.
Protect mode (typically a red LED) indicates an issue such as a short circuit in the speaker cables, overheating, low impedance, or a poor power/ground connection. Turn off the system to check all wiring and ensure the amp has adequate ventilation.
You should always use high-quality copper cable. While requirements vary by model, high-wattage single and multi-channel Crunch amplifiers often mandate 4-gauge power and ground cables. Check your specific owner's manual to confirm the recommended gauge.
