Hear the Difference!

Experience fidelity for all and crystal-clear audio in your boat or car with the xdm amplifier's exclusive dual-mode input filter and differential-balanced inputs for outstanding noise rejection, while the NEXD™ equipped advanced switching technology delivers reliable high-power output from a compact chassis by reducing current draw and heat, all benefiting from studio-grade signal processing featuring audiophile-grade, fully variable filters and calibrated potentiometers beneath a sealed security cover.

Uninterrupted Power and Built to Last!

With ADVANCED ROLLBACK PROTECTION, our innovative circuit design ensures the amplifier will never shut down due to thermal overload, keeping your music playing even under the most demanding conditions, all while offering flexible AUTO TURN-ON CAPABILITIES (via auto signal sensing, auto DC-offset sensing, or conventional +12 volt turn-on lead), and a BUILT TOUGH all-aluminum, powder-coated housing that inhibits corrosion and features a sealed security cover to protect controls from the elements.

Power Your Entire System!

Our amplifier line offers complete flexibility, featuring FULL-RANGE STEREO variants available in 2, 4, 6, and 8 channels, specialized SYSTEM AMPLIFIERS with 3 models that power a whole system using 2 or 4 full-range outputs plus a dedicated subwoofer output, robust MONOBLOCK options with 300, 600, and 1000 watts, and versatile 24-VOLT OPTIONS available in XDM600/6-24V and XDM800/8-24V channel variants.


Frequently Asked Questions (FAQ)


  • • Why does my JL Audio XDM300/1 turn on but my subwoofer doesn't produce any bass?
    Check the input source, low-pass crossover settings, and subwoofer wiring. A loose RCA connection is one of the most common causes.
  • • Can I run a 2-ohm subwoofer with the XDM300/1?
    Yes. The amplifier is designed to deliver its rated output into a 2-ohm load when wired correctly.
  • • Why does the amplifier shut off whenever the bass gets loud?
    This usually indicates low battery voltage, overheating, or a subwoofer load below the recommended impedance.
  • • Can I connect the XDM300/1 to a factory head unit without RCA outputs?
    Yes. The amplifier accepts high-level speaker inputs for simple integration with most factory audio systems.
  • • Why does my subwoofer sound muddy instead of tight and punchy?
    The crossover frequency, gain, or enclosure design may need adjustment for better bass response.
  • • Why do I hear engine noise through my subwoofer while driving?
    This is typically caused by poor grounding or RCA cables routed too close to the power cable.
  • • Can I use two 4-ohm subwoofers with the XDM300/1?
    Yes, provided they are wired to achieve a final impedance within JL Audio's recommended operating range.
  • • Why does the amplifier feel very hot after an hour of listening?
    Some heat is normal, but restricted airflow or prolonged high-output operation can raise amplifier temperature.
  • • Does the XDM300/1 support a remote bass level controller?
    Yes. It is compatible with JL Audio's optional HD-RLC remote bass control for convenient level adjustments.
  • • Why does the amplifier remain powered after I turn off the ignition?
    The remote turn-on wire is likely connected to constant 12-volt power instead of a switched accessory circuit.

  • Sound quality is really top notch with JL Audio. The sub sounds so much better with my new amp. There is much power from this tiny little amp. Good stuff from one of the best brands in the market.
