$1,099.99
4-Channel Class D Full-Range Amplifier, 150 W x 4 @ 1.5-4 Ω
This compact multi-channel powerhouse employs our Single-Cycle Control switching design and R.I.P.S. technology to deliver 150 W x 4 or 300 W x 2. Tight power supply regulation keeps distortion down and maximizes sound quality.
When using the HD750/1 or HD1200/1 to drive a subwoofer system, the HD600/4 is the ideal satellite amplifier, delivering huge dynamics with pristine resolution. 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.
It can also be deployed on its own as a very capable 3-channel system amplifier with 150 W x 2 to the satellites and 300 W x 1 to a subwoofer system.
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.

0 out of 5(0)Monoblock Class D Car/Marine Subwoofer Amplifier, 1000 W x 1 @ 2 Ω / 600 W x 1 @ 4 Ω – 14.4V
This monoblock subwoofer powerhouse employs our high-speed NexD switching technology to achieve unprecedented efficiency and amazing power output from a very compact chassis. The XDM1000/1 generates up to 1000 W of continuous power into a 2 ohm load (14.4V, 1% THD), making it a great choice to drive higher power subwoofer systems.
Designed for car or boat installations, the XDM1000/1 is built with marine-grade materials and features an exclusive, dual-mode input filter for noise-free performance in boats or cars. Automatic turn-on capability (via signal sensing or DC-offset sensing) is also onboard for easy factory system upgrades.
Intended specifically for subwoofer applications, the XDM1000/1 includes a variable slope low-pass filter with continuously variable cutoff frequency selection from 50-500 Hz and a defeatable infrasonic filter (30 Hz, 24 dB/oct.). With the addition of an optional HD-RLC or MHD-RLC (water-resistant) remote level controller (each sold separately), the amplifier’s level can be adjusted directly from the driver’s seat or captain’s chair.
Finished in a sleek, black powder-coat, all controls are protected beneath a gasketed, removable top cover for easy access.

Car AmplifiersJL AUDIO – XD500/3V2 3-channel car amplifier 75 watts RMS x 2 at 4 ohms + 300 watts RMS x 1 at 2 ohms
0 out of 5(0)3-Channel Class D System Amplifier, 75 W x 2 @ 4 ohm + 300 W x 1 @ 2 ohm – 14.4V
This compact amplifier is ideal for a simple audiophile-grade, subwoofer / satellite system. With the XD500/3v2, you can drive a pair of quality component speaker systems with plenty of clean power, while also delivering a stout 300 W to your subwoofer system. The breakthrough that makes this much power possible in such a small chassis is our NexD switching design.
The XD500/3v2 includes a 12 dB / octave high-pass filter for its main channels, plus a variable slope low-pass filter for its subwoofer channel. Both filters offer continuously variable cutoff frequency selection from 50-500 Hz.
The XD500/3v2 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.
