JL Audio RD1500/1 Car Monoblock Subwoofer Amplifier, 1500W 98643

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).
