Monoblock Class D Marine Wide-Range Amplifier, 750 W x 1 @ 1.5-4


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 , giving you the highest degree of flexibility in designing your subwoofer system.

Tight power supply regulation keeps distortion ultra-low and maximizes your bass performance. While targeted primarily to subwoofer applications, the MHD750/1 is a full-range amplifier and can also be used to drive high-performance mid and high frequency speaker systems.

This marine amplifier features white and gray powder-coat finishes, a gasketed cover for the controls and stainless steel hardware for durability in the marine environment.


Technology

Single Cycle Control™

High-Fidelity, full-range Class D is a reality.


R.I.P.S. - Regulated, Intelligent Power Supply

The remarkable R.I.P.S. System ensures consistent power delivery over a wide range of battery voltages and load impedances.


Advanced Rollback Protection

JL Audio's exclusive Advanced Rollback Protection circuit monitors the amplifier's thermal condition and adjusts amplifier operation to eliminate annoying amplifier shut-down events.


RealSink™

Vertical, cast alloy fins effectively dissipate heat, without resorting to noisy fan-cooling.


HD Mounting Options

Two mounting options plus a space-saving stacking feature ease installation.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
