JL Audio RD900/5+
RD car 5-channel system amplifier (900 watts)
SLEEK, POWERFUL, PACKED WITH VALUEThe 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.
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 an additional band-pass filter on its rear channels and a dedicated low-pass filter for the subwoofer channel. All 3 crossovers offer continuously variable frequency selection from 50–500 Hz for precise filtering.
LED CLIPPING INDICATOR RINGS
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.
BAND-PASS CROSSOVER
When used as a system amplifier, the band-pass crossover feature enables a two-way active configuration.
