More Power from a Smaller Chassis
The 4-channel JL Audio HD600/4 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.

I decided to get serious with my new car and the audio system and did a hell of a lot of research and it certainly paid off. This is the best amp I have ever had, and may I say I've been a DJ for 26 years and this JL HD600/4 amp can handle anything! Combined with JL C5650 Audio speakers and a 12" sub, the sound for me is just superlative with so much headroom and zero distortion. Thanks also to Sonic Electronix for such a great deal. Couldn't believe it until they arrived in my hands in Australia, but was so happy when it was the real deal. Highly recommended product and seller.

I dont personally run this amp, but a close friend of mine does whom ive helped install/tune his system. The size of the amp is pretty small, so you have more options for amp placement. This is a powerhouse to, and sounds great. The only complaint, is that it uses a connecter for the speaker terminals instead of wiring directly to the amp (this is me personally, its a lot easier for isntall purposes and you dont run the risk of stripping out the phillips screws on most amps). Overall, great amp, just a little pricey.

I have had many purchases through SonicElectronix and every time it has been a pleasure to do business with them. They have great prices, speedy delivery and their customer service is superb. My latest purchase was the JL Audio HD600/4 amp and it is a quality item. It is powerful and the audio clean, crisp and detailed. This amp will not let you down.
