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.

|I absolutely love my JL HD900/5 amp. The clarity is amazing. The best part about this amp is you power your speakers and sub from one compact amp. I was able to do a very discreet & clean install because of the amps small size. The quick disconnects make the amp easy to tune and remove to work on the car. I also add the remote bass knob to the amp which allows you to adjust your bass level at the twist of a knob mounted right next to the head-unit. Tuning this amp is very straight forward thanks to its labeling and good instructions provided. I have had this in my car for around 2 years so far and have not had one problem. I am powering 10 speakers and 1 JLW6V2 off this amp. This will be my amp of choice for my future hot rod purchases because of its power and compact size. I have been a JL fan since I started getting into stereos in 2005 and continue to be because I have not had one issue with any of their products and appreciate there great customer support.|

|I've had many amps but this JL audio HD900/5 is awesome. This thing does not lack in power, plenty of it! The sound quality is top notch. I highly recommend this amp to anyone wanting a compact but powerful 5 channel amp. Got a great deal through Online Car stereo so that was a no brainer...|
