About: JL Audio RD900/5 5-Channel Car Amplifier — 70W RMS x 4 + 500W RMS x 1

Sleek, Powerful, Packed with Value

The look is amazing, and the performance backs it up. Designed as a total “one-box solution,” this RD series amplifier from JL Audio can comfortably drive a complete 4-satellite speaker system plus a subwoofer — all with a robust 900 watts of power.

12-decibel/octave high-pass or band-pass filter with dedicated low-pass filter on subwoofer channel
Selectable input voltage: low (200 mV to 2-Volt RMS) to high (800 mV to 8-Volt RMS)
3 turn-on options: +12-volt remote wire, signal sensing or dc offset
Onboard led clipping indicator simplifies level setting
Signal routing flexibility with selectable input mode and type

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

Churning out 900 watts of total power — 100 watts from each of its 4 channels into a 2-ohm load (14.4 volts, 1% THD) plus a robust 500 watts for a subwoofer — this RD series amp brings stunning output to your audio system. Each pair of main channels is also fully bridgeable, enabling an ultrapowerful 3-channel amplifier setup.

Studio-Grade Signal Processing

Each of the amplifier’s main channels is equipped with a 12-decibel/octave high-pass filter, with a dedicated low-pass filter for its subwoofer channel. All 3 crossovers offer continuously variable frequency selection from 50–500 Hz for precise filtering.

LED Clipping Indicators

An LED clipping indicator light on the control panel lets you quickly set your amplifier’s input sensitivity, without the need for additional test equipment.

Easy Connectivity

With “input type” switches on the stereo channel sections, RD series amps can eliminate the need for Y-adapters when bridging stereo output channels.

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.
