JL Audio NexD™ Switching Technology

Experience powerful performance with 500 watts at 2 ohms or 250 watts at 4 ohms, all delivered with ultra-low distortion thanks to our innovative NexD™ Switching Technology. Housed in a sleek, ultra-compact design with a durable black powder-coated finish, this amplifier combines high output with refined efficiency for pure subwoofer bliss.

Effortless Control and Advanced Audio Customization with Variable Bass Boost

Enjoy easy access to top-mounted controls, neatly protected under a sleek cover, while advanced signal processing with a 12 dB/octave low-pass filter lets you fine-tune frequencies from 50-500 Hz. Take your sound to the next level with a variable bass boost EQ for enhanced bass control and customized audio.

Seamless Integration and Effortless Activation with Versatile Inputs and Preamp Outputs

With versatile dual-range, differential-balanced inputs that accept most voltage levels, this amplifier ensures seamless integration. Automatic turn-on via signal or DC-offset sensing makes activation effortless, while preamp outputs allow you to easily pass signals to additional amplifiers for a more powerful audio setup.

Quick Sensitivity Adjustment and Real-Time Status Monitoring with Optional Remote Control

Easily set input sensitivity with the onboard LED clipping indicator, while the top-mounted dual-color LED light strip keeps you informed of the amplifier’s status at a glance. For added convenience, pair it with the optional RBC-1 remote control (sold separately) to adjust subwoofer output directly from the driver’s seat.

FEATURES


Features:

  • EFFICIENT CLASS-D DESIGN: Small size, minimal heat and lots of power — Class-D amplifier design offers significant advantages. And our NexD switching technology adds even more, using enhanced pulse width modulation techniques to boost the amplifier’s bandwidth while minimizing distortion and improving efficiency.
  • CLEAN, POWERFUL, RELIABLE: With a choice of 500- or 1000-watt versions — stable to 2 ohms, or a 1500-watt version stable to 1 ohm — the RD series offers a variety of models to drive your subwoofer. The high-efficiency design enables them to run cooler and put less strain on your electrical system than conventional amplifiers.
  • STUDIO-GRADE SIGNAL PROCESSING: For easy setup and interface with your speaker system, the RD series features a 12-decibel/octave low-pass filter, with continuously variable frequency selection from 50–500 Hz and a variable bass boost EQ.
  • LED CLIPPING INDICATOR RINGS: An LED clipping indicator ring that surrounds each input level potentiometer lets you quickly and accurately set your amplifier’s input sensitivity, without the need for additional test equipment.
  • AUTOMATIC TURN-ON FEATURE: This helpful feature, selectable between signal sensing and DC offset sensing modes, comes standard on all RD series amps.
  • DIFFERENTIAL-BALANCED INPUTS: Combating induced cable noise, this technology allows for the use of conventional RCA cables while delivering many of the benefits of a true balanced connection and accepting a wide range of input signal levels.
  • NexD SWITCHING TECHNOLOGY: Using enhanced pulse width modulation techniques, NexD technology achieves exceptional audio fidelity and efficiency while delivering high-power output from very compact amplifier designs.

  • Fantastic little amp. This is actually my second one after I had a factory wiring issue going to a LOC and then the amp. Last one was just shy of 5 years old before it tapped out. It’s currently more than enough for my loaded JLTW3 sub box.

  • I thought it was huge as it is a 500 Watt rated amp but to my surprise it has a compact design which makes it easier to place in my tightly spaced car. Paired my JL Audio sub to it and its really booming better. Not really that expensive too considering what it can do and it is a JL Audio amplifier.
