JL Audio HD600/4 600W 4 Channel Class D Full-Range Amplifier

4-Channel Class D Full-Range Amplifier, 150 W x 4 @ 1.5-4 Ω

This compact multi-channel powerhouse employs our Single-Cycle Control switching design and R.I.P.S. technology to deliver 150 W x 4 or 300 W x 2. Tight power supply regulation keeps distortion down and maximizes sound quality.

When using the HD750/1 or HD1200/1 to drive a subwoofer system, the HD600/4 is the ideal satellite amplifier, delivering huge dynamics with pristine resolution. 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.

It can also be deployed on its own as a very capable 3-channel system amplifier with 150 W x 2 to the satellites and 300 W x 1 to a subwoofer system.

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.

JL Audio HD600/4 Making an amplifier small is great, of course, but not if power and sound quality are sacrificed.

This is why JL Audio's engineering team focused on achieving world-class fidelity first, and then on making the HD amplifiers amazingly powerful, efficient and small. These efforts led to a remarkable switching amplifier technology called Single Cycle Controlâ¢, which allows all of these goals to be achieved.

This exclusive core amplifier technology is mated to JL's regulated, intelligent power supply (R.I.P.S.), advanced thermal management systems and a full complement of studio-grade processing features to put the all-new HD600/4 amplifiers in a performance class all their own.

JL Audio invite you to sonically compare the HD amplifiers to any amplifier, at any price... They think you will quickly discover that all the old amplifier compromises have suddenly vanished.

The JL 4-channel HD600/4 amplifier pushes 150 watts RMS per channel to your speakers or subs, from a 2" tall chassis that's about the size of a sheet of computer paper. The regulated power supply allows this amp to deliver its rated power to a wide range of impedances, even when voltage levels drop during heavy use. Removable power and speaker plugs make it easy to pop this amp out if you need the space in your boot area.
