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.

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.
