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.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eJL Audio technology goes to work for you\u003c\/h2\u003e\n\u003cp\u003eHD 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.\u003c\/p\u003e\n\u003ch2\u003e4 channels of reliable power\u003c\/h2\u003e\n\u003cp class=\"clearfix\"\u003eThe 4-channel HD600\/4 amplifier pushes 150 watts RMS per channel to your speakers or subs, 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 cargo area.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eSome extra touches\u003c\/h2\u003e\n\u003cp\u003eYou can use JL Audio's optional\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/www.crutchfield.com\/Product\/Item\/Main.aspx?I=136HDSTKIT\"\u003estack kit\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003eto mount one HD Series amp on top of another, so you can maximum power from minimum space.
