JL  Audio's most power amplifier ever employs their advanced Single-Cycle Control switching design and R.I.P.S. technology to deliver 1200 W (RMS) of clean power into any impedance between 1.5 and 4 Ω, giving you the highest degree of flexibility in designing your subwoofer system. Tight power supply regulation keeps distortion down and maximizes your bass 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.
