JL Audio HD900/5 5 Channel Class D Amplifier
JL Audio HD900/5
5-Channel Class D System Amplifier, 100 W x 4 + 500 W x 1
Thanks to its ability to act as a “one-box solution”, the HD900/5 is ideal for installations where space is at a premium and sound quality is the paramount goal.
While extremely compact, this amazing amplifier will comfortably drive a complete high-performance car audio system: that is, four satellite speaker systems and a subwoofer system… with a very serious 900 watts of power!
Using our Single Cycle Control switching design and R.I.P.S. technology, the HD900/5 delivers 100 W x 4 to its four main channels, plus a very meaty 500 W to its subwoofer channel. Thanks to R.I.P.S., high power can be delivered over a wide range of load impedances, while the tight power supply regulation keeps distortion down, maximizing sound 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.
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.
