Monoblock Class D Wide-Range Amplifier, 1200 W x 1 @ 1.5-4 Ω

Our most powerful HD amplifier employs our advanced Single-Cycle Control switching design and R.I.P.S. technology to deliver 1200 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 HD1200/1 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.

Technology
Single Cycle Control™ (U.S. Patent #6,084,450*)

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.

Differential-Balanced Inputs

JL Audio's Differential-Balanced Inputs are engineered to combat induced cable noise, which is a common problem in car and marine audio installations. This technology allows for the use of conventional RCA cables, while delivering many of the benefits of a true balanced connection and accepting a wide range of input signal levels.

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.
