750W x 1 @ 4Ω

HD-Series Monoblock Class-D Wide-Range Amplifier, 750-Watts x 1ch @ 1.5-4-Ohms This ultra-compact monoblock amplifier employs JL's Single-Cycle Control switching design and R.I.P.S. technology to deliver 750W of clean power into any impedance between 1.5 and 4Ω, giving you the highest degree of flexibility in designing your subwoofer system. Tight power supply regulation keeps distortion down and maximizes your bass quality. From a pure sound quality perspective, JL invites you to compare the real-world, in-car performance of this amplifier to any other amplifier on the market, of any type, at any price. While targeted primarily to subwoofer applications, the HD750/1 is a wide-range amplifier and can also be used to drive high-performance mid-range speaker systems. This amplifier features a brushed aluminum finish with black powder-coated cast alloy heat sinks and bottom panel. A black powder-coated, gasketed cover is also provided to protect the controls.

RD-Series 1500-Watt Monoblock Class-D Subwoofer Amplifier @ 2-Ohms 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). Specifications Frequency Response 7 Hz - 500 Hz (+0, -1dB) S/N Ratio, referred to highest rated power >82 dB below rated power (A-weighted, 20 Hz - 20 kHz noise bandwidth) S/N Ratio, referred to 1 W >50 dB (A-weighted, 20 Hz - 20 kHz noise bandwidth) Damping Factor @ 4 Ω >1100 / 50 Hz Damping Factor @ 2 Ω >550 / 50 Hz THD+N @ Rated Power <1% @ 2 Ω per Ch.
