JL Audio HD750/1 1 Ch. 750 Watt 4 Ohm Monoblock Amplifier – #98220

HD750/1 Monoblock Class D Wide-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 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.

Small amps, big power

JL Audio’s HD750/1 amplifiers offer high performance from an ultra-compact chassis. These Class D amplifiers use less power, take up less space, and generate less heat than traditional amp designs — you can even stack them up to create a sweet-looking installation.

JL Audio technology goes to work for you

HD750/1 amplifiers reproduce your music with exceptional accuracy, so you’ll hear high-fidelity sound even under the most demanding conditions. JL Audio uses Single Cycle Control™ technology to eliminate the excessive signal distortion that’s plagued Class D amplifiers in the past. Differential-balanced inputs eliminate noise before it hits the preamp stage, and allow you to connect the amp to just about any in-dash stereo. You’ll hear clear, true, studio-quality audio, exactly what you expect from JL Audio.

Reliable power for your subs

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 (1.5 to 4 ohms), 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 cargo area.

Some extra touches

You can use JL Audio’s optional stack kit to mount one HD750/1 amp on top of another, so you can maximum power from minimum space. JL’s wired remote allows you to control your HD amp’s volume from your front seat.
