JL Audio RD1500/1 Monoblock Class D Subwoofer Amplifier, 1500 W

Sleek and powerful, RD amplifiers offer outstanding amplifier performance and value.

RD amplifiers employ JL Audio’s exclusive NexD™ switching technologies to generate loads of power with exceptional efficiency, reducing current draw and heat. Each model features a modern, industrial design with a high performance look and finish. For ease of installation and making adjustments, all connections are placed along one side of the amplifier with the controls on top, concealed beneath a removable protective cover.

All RD models are equipped with studio-grade signal processing and automatic turn-on capabilities (via signal sensing and DC-offset sensing), for maximum flexibility. Differential-balanced inputs are also on-hand to combat noise and maximize compatibility with a wide range of signal types. Two additional features have been included to simplify installation and set-up: LED clipping indicators to streamline the input level setting process, and "Input Type" switches on the stereo channel sections, eliminating the need for Y-adaptors when bridging.

The look is amazing, and the performance backs it up.

Monoblock Class D Subwoofer Amplifier, 1500 W x 1 @ 1 - 2 Ω / 750 W x 1 @ 4 Ω - 14.4V

Engineered for high-power, subwoofer applications, the RD1500/1 monoblock amplifier is built to deliver staggering amounts of world-class bass output. Equipped with a special low impedance circuit, the RD1500/1 is capable of generating a whopping 1500 watts of output power, at either 1 or 2 ohms (14.4V, 1% THD). At the heart of this ultra-sleek and compact power plant is JL Audio’s exclusive NexD™ Class D technology, permitting high power output with exceptional efficiency and low distortion.

For your convenience, all of the RD1500/1’s controls are located on top of the amplifier, beneath a protective cover, with all connections found along one side of its chassis. Signal processing features include a 12 dB / octave low-pass filter, with continuously variable frequency selection from 50-500 Hz, and a variable bass boost EQ. Dual-range, differential-balance inputs are also onboard, capable of accepting most input voltage levels. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard, along with a set of preamp outputs so you can easily pass signals to another amplifier.

The RD1500/1 is also equipped with an onboard LED-clipping indicator. This all-new, innovative feature lets you easily set your amplifier’s input sensitivity setting, quickly and accurately, with no special equipment needed. The RD1500/1 features a durable, black powder-coated finish and a top-mounted, dual-color LED light strip that reports the overall status and condition. Control of the subwoofer level from the driver’s seat is easily accomplished with the addition of the optional RBC-1 remote level control (sold separately).
