JL Audio HD Series HD750/1 Mono subwoofer amplifier — 750 watts RMS x 1

Small amps, big power

JL Audio’s HD Series 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

HD Series 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 kitto mount one HD Series amp on top of another, so you can maximum power from minimum space. JL’s wired remoteallows you to control your HD amp’s volume from your front seat.
