More Power from a Smaller Chassis
The 5-channel JL Audio HD900/5 HD series car amplifier delivers unreal power in a very small and convenient size. Often times smaller amplifiers will lack power or even quality, however with the new JL Audio HD amplifiers this will not be the case. The HD amplifiers are equipped with amazing technologies like Single Cycle Control, which tracks audio signal and compares it to the real PWM waveform and then corrects it accordingly each and every cycle. This helps to control distortion causing mechanisms improving the quality of the amplifier tremendously. HD amplifiers also feature the R.I.P.S. System, R.I.P.S. stands for "Regulated, Intelligent Power Supply" and ensures consistent power delivery over a wide range of battery voltages and load impedance's. This means you will received the same power output at 4 ohms all the way down to 1.5 ohms each and every single time. With dual mounting options for added versatility and advanced heatsinks with vertically oriented fins for extreme heat control, the JL Audio HD amplifiers are unmatched by other amplifiers in the same class.

This amp is just awesome.. Small and powerful and does not run hot. I have it running 2 Image Dynamics 10's and 4 Boston Acoustics 6". Never misses a beat!

I purchased this JL Audio HD900/5 amp because it had the option to power four door speakers along with a sub woofer. It works great. I have it powering the four speakers in the doors and have the 5th channel powering the sub in the back.

I chose this five channel amp to save space in my Ranger Supercab truck. It powers four speakers in the doors and a JL Audio 10 inch W/6 sub and and it is smaller than most high school textbooks. This amp amazes me every time I crank up the volume. The sound is clean and there is just so much power it's hard to believe it all comes from this little amp. It has a hefty price, but if you want great sound without a big stack of amps, you should consider the JL HD900/5.

I bought this unit and paired it with an Aline IVA-W505, Polk speakers and a JL W6 enclosed sub. The amp is absolutely clean way past reasonable listening levels. The highways in my area are horrible due to studded tires in the wintertime. This makes for a tremendous amount of road noise. The amp will drive the system cleanly past ALL road noise which is just incredible.
I highly recommend the product. When I sell my car the amp goes with me!

I cannot believe how powerful this amp is for its size. It is so compact it fits under my front seat without blocking the rear seat vents. The only thing I don't like it the lack of the Q, and the infrasonic dial has gone to a switch.
