JL Audio HD750/1 Monoblock Class D Wide-Range Amplifier, 750 W

Monoblock Class D Full-Range Amplifier, 750 W x 1 @ 1.5-4 Ω

This ultra-compact monoblock amplifier employs our Single-Cycle Control switching design and R.I.P.S. technology to deliver 750 W of clean power into any impedance between 1.5 and 4 Ω, 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, 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.

While targeted primarily to subwoofer applications, the HD750/1 is a full-range amplifier and can also be used to drive high-performance mid and high frequency 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.

JL Audio HD750/1 Making an amplifier small is great, of course, but not if power and sound quality are sacrificed.

This is why JL Audio's engineering team focused on achieving world-class fidelity first, and then on making theJL HD amplifiers amazingly powerful, efficient and small. These efforts led to a remarkable switching amplifier technology called Single Cycle Controlâ¢, which allows all of these goals to be achieved.

This exclusive core amplifier technology is mated to JL's regulated, intelligent power supply (R.I.P.S.), advanced thermal management systems and a full complement of studio-grade processing features to put the all-new HD amplifiers in a performance class all their own.

JL Audio invite you to sonically compare theHD750/1 amplifier to any amplifier, at any price... They think you will quickly discover that all the old amplifier compromises have suddenly vanished.

The HD750/1 class D mono amplifier pushes 750 watts RMS to your sub, from a 2" tall chassis that's about the size of a sheet of computer paper. The regulated power supply allows this amp to deliver its rated power to a wide range of impedances, even when voltage levels drop during heavy use. Removable power and speaker plugs make it easy to pop this amp out if you need the space in your boot area.
