Frequently Asked Questions (FAQ)


  • • Why won't my JL Audio MHD600/4-24V power on after installing it in my 24-volt boat?
    Check the 24V power supply, fuse, ground connection, and remote turn-on lead. Low voltage or poor grounding is the most common issue.
  • • Can I use the MHD600/4-24V in a standard 12-volt vehicle?
    No. This amplifier is specifically designed for 24-volt electrical systems and should not be used on 12-volt vehicles.
  • • Why do channels 3 and 4 have no sound while channels 1 and 2 work normally?
    Check the input mode and signal routing switches. Incorrect input configuration is a common installation mistake.
  • • Can I bridge the amplifier to power two high-output speakers?
    Yes. The MHD600/4-24V supports bridged operation when wired within JL Audio's recommended impedance specifications.
  • • Why does the amplifier become very warm during long days on the water?
    Some heat is normal, but restricted airflow or low speaker impedance can cause excessive operating temperatures.
  • • Why do I hear a whining noise that changes with engine speed?
    This is usually caused by a grounding issue or signal cables routed too close to power wiring.
  • • Can I run four 2-ohm marine speakers with this amplifier?
    Yes. The amplifier is stable at 2 ohms per channel when used in its normal four-channel configuration.
  • • Why does the Protection LED illuminate after I connect new speakers?
    A shorted speaker wire or impedance below the recommended limit is the most common cause.
  • • Is the MHD600/4-24V waterproof enough to mount on an open deck?
    No. It is marine-rated for moisture resistance but should still be installed in a protected, well-ventilated location.
  • • Why do my speakers sound distorted only when both bridge channels are being used?
    The bridged speaker load may be too low or the amplifier gain may be set too high. Verify the wiring and readjust the gain settings.
