JL Audio's RD Series Amplifiers
Class D Power for Days


JL Audio RD500/1 Monoblock Class D Amplifier

Lots of power, installer-friendly design and options for every audio enthusiast, all make it easy to choose a JL Audio RD Series amplifier.


RD500/1

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 amplfier 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


RD900/5

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.

For an amp that delivers power, utility, simplicity and plenty of options, take a look at all of the JL Audio RD Series amps at Sonic Electronix. We’re sure you’ll end up with one in your cart.

What’s not to love?

The following review is for RD500/1, which is a part of the bundle you are viewing.

This little amplifier is absolutely amazing! It is very small and delivers a very solid amount of power. I have this driving a JL 12 W3V3, and it is very capable of driving it to its limit, all while remaining as cool as a cucumber. This thing, regardless of how hard you push it, never seems to even get warm. Add to the incredible performance the capability of setting the gain easily using the included clip indicator light, and you have an absolute joy to deal with. I highly recommend this amplifier. Oh, one last thing; the optional remote knob is an absolute must.
