JL Audio XDM500/3 3 Channel 500 W Class D Car/Marine System Amplifier – #98682

XDM500/3: 3-Channel Class D Car/Marine System Amplifier, 75 W x 2 @ 4 Ω + 300 W x 1 @ 2 Ω – 14.4V

Small enough to fit in just about any tight space application, the XDM500/3 is the perfect amplifier for a simple audiophile-grade, subwoofer / satellite system. With its three channels of versatile output, you can drive a pair of quality component speaker systems with plenty of clean power, while also delivering a stout 300 W to your subwoofer system. The technology that makes this much power possible in such a small chassis is our advanced NexD™ switching amplifier design.

Suitable for car or boat installations, the XDM500/3 is built with marine-grade materials and features an exclusive, dual-mode input filter for noise-free performance in boats or cars. Automatic turn-on capability (via signal sensing or DC-offset sensing) is also onboard for easy factory system upgrades.

The XDM500/3 includes a 12 dB / octave high-pass filter for its main channels, plus a variable slope low-pass filter for its subwoofer channel. Both filters offer continuously variable cutoff frequency selection from 50-500 Hz. With the addition of an optional HD-RLC or MHD-RLC (water-resistant) remote level controller (each sold separately), you have the ability to adjust the level of all amplifier channels or just the subwoofer channel directly from the driver’s seat or helm.

Finished in a sleek, black powder-coat, all controls are protected beneath a gasketed, removable top cover for easy access.

One Amp for Land or Sea!

  • Marine-grade materials on every model for maximum application versatility from just one amplifier line.
  • Exclusive, dual mode input filter, for noise-free performance in boats OR cars, every time!
  • Automatic turn-on option via Signal-Sensing or DC-Offset sensing
  • All controls on top, beneath a gasketed, removable cover for easy access.
  • Compact Design / Amazing Versatility: Fits nearly anywhere: 8.52 x 7.09 x 2.05 in. (217 x 180 x 52 mm).

NexD Switching Amplifier Technology

  • Our advanced switching technology delivers exceptional efficiency to reduce current draw and heat, permitting reliable high power output from a compact, easy to install design.
  • Ultra-high speed switching and control circuitry delivers super- clean full-range audio with very low distortion and noise.

Studio-Grade Signal Processing

  • 12dB/octave high-pass filter for for the main channel bank with fully-variable frequency selection from 50-500 Hz via detented, calibrated potentiometer.
  • 12dB or 24dB/octave low-pass filter for the subwoofer channel with fully-variable frequency selection from 50- 500 Hz via detented, calibrated potentiometer.
  • Optional remote level controllers (HD-RLC or MHD-RLC). Assignable to all three channels or subwoofer channel only.
  • Preamp outputs (pass-through type)

Advanced Rollback Protection

  • Amplifier will never shut down due to thermal overload. EVER.
  • Totally transparent to user in most cases… Restores full power operation when it has cooled down to safe temperature.
  • Unitary Cast Alloy Chassis for superior heat dissipation and mechanical integrity.

Here are a few examples of how the XDM500/3 can be used:

  • Drives main speakers with 75W x 2, plus a subwoofer system with up to 300W
  • Ideal for systems in small vessels, UTVs, pickup trucks or sports cars
