This ultra-compact monoblock amplifier employs our Single-Cycle Control switching design and R.I.P.S. technology to deliver 750 W 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. While targeted primarily to subwoofer applications, the HD750/1 is a wide-range amplifier and can also be used to drive high-performance mid-range speaker systems.

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.

Have 2 of them powering 4 12w3's and it's the loudest/cleanest hard hitting system I've ever had and over the past 23 years I've had plenty of systems

I have the JL hd750/1 Powering my 12w7. I must say, wow!!!! I was a little skeptical about the power difference compared to the initial 500/1 setup that i had. There was a total difference from the time i powered the amp, and it has not let me down yet. Amazing amp
