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 \u003cp style=\"text-align: left;\"\u003e\u003cstrong\u003eReliable power for your subs\u003c\/strong\u003e\u003c\/p\u003e \u003cp class=\"clearfix\" style=\"text-align: left;\"\u003eThe 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.
