Frequently Asked Questions (FAQ)


  • • Why does the amp go into protection mode?
    Protection can be caused by overheating, a low speaker load, shorted wiring, or poor power and ground connections. Check impedance, terminals, ventilation, and wiring before operating the system again.
  • • Why does it shut off when I turn up volume?
    A shutdown at higher volume may indicate insufficient current, overheating, or an unsuitable subwoofer load. Check the battery, charging system, power wiring, ventilation, and final speaker impedance before raising output.
  • • Why is there no bass when the amp turns on?
    Check the RCA connections, gain, low-pass filter, remote turn-on, and subwoofer wiring. Confirm the head unit is sending a signal and make sure the speaker terminals are secure with correct polarity.
  • • Why does the amp get too hot?
    Some heat is normal, but excessive temperature can indicate poor airflow, a low impedance load, or prolonged high output. Improve ventilation and verify the connected subwoofer meets the recommended impedance.
  • • Why does the subwoofer sound distorted?
    Distortion can result from excessive gain, bass boost, or clipping from the source. Lower the gain and EQ settings, then confirm the amplifier receives a clean signal and the subwoofer is properly matched.
  • • Why do I hear engine noise from the sub?
    Engine-speed-related whining is often linked to grounding or signal interference. Check the amplifier ground and RCA connections, and route signal cables away from power wiring to reduce unwanted electrical noise.
  • • Can I use a dual voice coil subwoofer?
    Yes, as long as the voice coils are wired to create a final impedance supported by the amplifier. Calculate the resulting load before connecting, since too-low impedance can trigger protection or excessive heat.
  • • Why is the subwoofer output weaker than expected?
    Check the gain, input signal, speaker wiring, enclosure, and final impedance. Also verify the power and ground cables are properly sized and secure, since inadequate electrical supply can limit output.
  • • Why does the bass change after adjusting the crossover?
    The low-pass filter controls which frequencies reach the subwoofer. If set too high or low, bass may sound muddy or weak. Adjust it gradually until the sub blends smoothly with the main speakers.
  • • What should I check if the amp suddenly stops?
    Check the main fuse, power and ground connections, remote turn-on wire, and speaker wiring. If those are secure, inspect for overheating or protection activation before reconnecting and testing the system.

  • Been running my sub with this amp for more than a month now and its really sounds better than my old amp. Before, I was planning to replace my sub as I’m not getting the lows that I’m looking for but when I got to try this out, the sub delivers a new dimension of bass that I did not know it can bring out.
