JL Audio HD Series HD1200/1 Mono subwoofer amplifier — 1,200 watts RMS x 1

5-Channel Class D System Amplifier, 100 W x 4 + 500 W x 1

Thanks to its ability to act as a “one-box solution”, the HD900/5 is ideal for installations where space is at a premium and sound quality is the paramount goal.

While extremely compact, this amazing amplifier will comfortably drive a complete high-performance car audio system: that is, four satellite speaker systems and a subwoofer system… with a very serious 900 watts of power!

Using our Single Cycle Control switching design and R.I.P.S. technology, the HD900/5 delivers 100 W x 4 to its four main channels, plus a very meaty 500 W to its subwoofer channel. Thanks to R.I.P.S., high power can be delivered over a wide range of load impedances, while the tight power supply regulation keeps distortion down, maximizing sound quality. From a pure sound quality perspective, we invite 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.

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.

5-Channel Class D System Amplifier, 100 W x 4 @ 2 ohm + 600 W x 1 @ 2 ohm – 14.4V

The XD1000/5v2 delivers up to 1000 W of clean power and is ideal for an audiophile-grade, subwoofer + four satellite system. With this potent amplifier, you can drive two pairs of quality component speaker systems with plenty of clean power (75 W x 4 @ 4 ?), while also delivering a stout 600 W of power to a subwoofer system. The breakthrough that makes this much power possible in such a small chassis is our NexD switching amplifier design.

The XD1000/5v2 includes a 12 dB / octave high-pass filter for one main channel pair, a 12 dB octave high-pass or bandpass filter for the other main channel pair, plus a variable slope low-pass filter for its subwoofer channel. All three filters offer continuously variable cutoff frequency selection from 50-500 Hz. This amplifier’s filters can also be configured as a true 3-way crossover, with a low-pass filter for the subwoofer channel, a bandpass filter on Ch. 3 & 4, and a high-pass filter on Ch. 1 & 2. An “x10” multiplier switch on the Ch. 1 & 2 high-pass filter allows its cutoff frequency to be adjusted from 50-500 Hz or 500-5000 Hz.

The XD1000/5v2 also features the v2 Spec feature set, which consists of automatic turn-on capability (via signal sensing or DC-offset sensing), and a dual-range differential-balanced input section able to handle a wide range of input voltage levels. With the addition of an HD-RLC remote level control (sold separately), the amplifier’s level can be directly controlled from the driver’s seat.

This amplifier features a black powder-coat finish and a gasketed, brushed aluminum cover for the controls.
