JL Audio RD1000/1 RD Series 1000W RMS Class-D Mono Subwoofer Amplifier with NexD™ Technology

Powerful, Efficient Class-D Performance

Bring powerful bass to your car audio system with the JL Audio RD1000/1 mono subwoofer amplifier. Featuring NexD™ Class-D switching technology, this amplifier delivers up to 1000 watts RMS at 2 ohms or 600 watts RMS at 4 ohms, combining high output with efficient operation and low distortion. Its compact design makes it a practical choice for systems that demand substantial subwoofer power.

Adjustable Crossover and Bass Control

Customize your subwoofer performance using the built-in 12 dB/octave low-pass filter, adjustable from 50 to 500 Hz. The variable bass boost EQ provides additional control over low-frequency response, helping you tailor the sound to your subwoofer, enclosure, and listening preferences. Convenient top-mounted controls make system adjustments easier during installation and tuning.

Flexible Inputs and Automatic Turn-On

The RD1000/1 features dual-range, differential-balanced inputs designed to accommodate a variety of source signal levels while helping reduce unwanted noise. Automatic turn-on options using signal sensing or DC-offset sensing provide convenient integration with compatible audio systems, simplifying installation in different vehicle configurations.

Clean Signal Pass-Through and Clipping Monitoring

Built-in preamp outputs allow the audio signal to pass to additional amplifiers, making it easier to expand your system. The onboard LED clipping indicator helps with input sensitivity adjustment, while the top-mounted dual-color LED status strip provides a convenient visual reference for amplifier operation.

Compact Design with Optional Remote Control

Designed for high-power subwoofer applications, the RD1000/1 combines a compact chassis with accessible top-mounted controls. Add the optional JL Audio RBC-1 remote control, sold separately, to adjust subwoofer output conveniently from the driver's seat.

Take Your Bass System Further with JL Audio

Choose the JL Audio RD1000/1 for powerful mono amplification, efficient NexD™ technology, and flexible sound customization. With up to 1000 watts RMS at 2 ohms, built-in crossover controls, and convenient signal monitoring, this amplifier is designed to deliver impressive bass performance in your compatible car audio system.

Premium Styling: Black powder-coat finish with brushed aluminum control cover for a sleek, professional look
Mono Class-D Subwoofer Amp: RD1000/1 is a mono Class-D amplifier designed specifically for subwoofers, stable down to 2Ω
High RMS Output: Produces 600W RMS @ 4Ω, 800W RMS @ 3Ω, and 1000W RMS @ 2Ω at 14.4V (adjusted slightly lower at 12.5V)
Differential-Balanced Inputs: Minimizes noise and alternator whine, allowing direct connection to most OEM source units
Speaker-Level Ready: Compatible with speaker-level outputs using a speaker wire to RCA adapter (sold separately)
Intelligent Protection System: Bi-color LED indicates power-up, normal operation, thermal protection, over-current events, and voltage shutdown
Temporary Red LED: Lights for 3 seconds during power-up, muting audio to protect the system
Constant Blue LED: Indicates normal amplifier operation
Constant Red LED: Indicates thermal overload; amplifier mutes until safe temperature is restored
Momentary Red LED: Flashes for ½ second during over-current conditions caused by low impedance or wiring shorts
Automatic Restart: LEDs off only when battery or remote voltage drops below 10V; amplifier resumes normal operation above 11V
Efficient Cooling System: Aluminum shell dissipates heat effectively; avoid enclosing in small, poorly ventilated spaces
Secure Control Panel Cover: Brushed aluminum cover protects settings and maintains a clean aesthetic
Onboard LED Clipping Indicator: Quickly and accurately sets input sensitivity without special tools
