Lots of power, installer-friendly design and options for every audio enthusiast

The Monoblock RD500/1 has the do-it-yourself audiophile completely in mind. Capable of pushing out up to 500 watts of clean power at 2 ohms, this subwoofer amplifier handily powers all the low end you can stand.

The RD Monoblocks have built-in 12 dB/octave low-pass filters, bass equalizer boosters and three turn-on modes: Traditional 12-volt trigger, signal sensing and DC offset.

Top off the package with a sleek, single-cast piece of aluminum in black powdercoat and blue LEDs, and your power looks as clean as it sounds.

Designed For Installers

JL Audio’s engineers had professional and at-home installers in mind with the RD Series. All of the inputs and controls are on the same side of the chassis, simplifying the setup whether you’re in a shop or in your driveway.

The output clipping indicators on each channel section mean you don’t need specialized tools to accurately set the gain.

A remote level control input gives you the option to install a bass level knob, sold separately, in the front seat, giving you full control over the bass output for every song you play.


NexD™ Switching Technology

NexD™ Switching Technology

The RD Series also incorporates JL Audio’s NexD Switching Tehnology. Since Class D amplifiers have a tendency to produce distortion at some ranges, NexD Switching helps cancel it out before feedback is ever applied.

All of this helps ensure the some of the cleanest possible signal to your subwoofer from your brand new Class D amplifier.
