JL Audio HD900/5 Class D 5 Channel Amplifier System (HD900/5)

HD900/5 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.

Small amps, big power

JL Audio’s HD Series amplifiers offer high performance from an ultra-compact chassis. These HD900/5 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

HD900/5 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.

Power your entire system with one compact amp

The 5-channel HD900/5 amplifier pushes 100 watts RMS per channel to your front and rear full-range speakers, plus 500 watts RMS to a sub — all from a 2″ tall chassis that’s about the size of a sheet of computer paper. Or, you can bridge the front and rear channels to drive 150 watts RMS into two speakers, while still running your sub at 500 watts.

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 cargo area.

Some extra touches

You can use JL Audio’s optional stack kit to mount one HD900/5 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.
