Quality, Efficiency, and Convenience with JL Audio XD Amplifiers

JL Audio's XD600/6 6-channel XD series amplifier encompasses high quality at an affordable price. When JL Audio sets out to make an affordable amplifier the one thing that you can bet they will not do is compromise on quality and performance. XD amplifiers feature NexD Class D Technology, that reduces distortion and increases efficiency. The use of an Advanced Rollback Protection system will allow the XD amplifiers to maintain both thermal and low-impedance protection by either limiting available peak voltage when overheating or rolling back peak voltage when low impedance is presented at the outputs. In order to minimize engine whine or alternator noise, XD amplifiers feature differential-balanced inputs that eliminate voltage sensitivity between one input terminal and ground thus reducing the occurrence of interference. Apart from all these great technologies, XD amplifiers also feature a relatively small chassis, making them easily mountable in any vehicle without extraneous hassle. When looking for a space-saving amplifier loaded with the latest technologies and unsurpassed quality and performance, then look no further than JL Audio's XD series car amplifiers.

Power Specifications - Full Range Channels

RMS Power @ 4 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

75 watts x 6 channels
RMS Power @ 2 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

100 watts x 6 channels
Bridged RMS Power

Bridging refers to combining two channels on an amplifier to create one channel with double the voltage and an increased power output. A 2-channel amplifier will bridge down to 1-channel and a 4-channel amplifier can bridge to create 2-channels. An amplifier is most commonly bridged to drive a subwoofer.

Remember, once you bridge two channels down to one its final impedance will be 4 ohms unless otherwise specified. This rating lists the RMS power created once an amplifier is bridged.

200 watts x 3 channels

Amplifier Specifications

Amplifier Series
This designates the series of the amplifier. Many amps are available in a litany of different wattage and channel configurations, but maintain consistent features throughout the product line.
XD (JL Audio)
Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

D
Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.

Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.

RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.

The RMS output figure is much more accurate than the peak rating when comparing products.

600 watts
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
4 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
2 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
4 ohms
THD at Rated RMS Power
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
1.0%
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
No
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
1 pair
Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Low-pass (LP)
High-pass (HP)
High-Pass Crossover Frequency
The high-pass crossover frequency can be a fixed crossover point or a variable crossover range. A variable high-pass crossover allows you to select a specific crossover point which allows frequencies above the set crossover point to pass, while making frequencies below the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

50 - 500 Hz
Low-Pass Crossover Frequency
The low-pass crossover frequency is typically used for subwoofers. It can be a fixed crossover point or a variable crossover range. A variable low-pass crossover allows you to select a specific crossover point which allows frequencies below the set crossover point to pass, while making frequencies above the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

50 - 500 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
>104 dB
Bass/Gain Remote
If the amp comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
Optional (Accessory required and sold separately)
Fan Cooled
A great feature to have if an amp generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the amp from overheating (burning).
No
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
50A x 1 
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

Great Amp

June 12, 2013

I put this in a BMW along with Jehnert speakers. It is amazing how much better it sounds! The small footprint allows you to get creative with your installation, and the amp puts out clean sound as loud as you wish. Best amp I have had especially when the low price is considered.

Awesome amp

September 7, 2012

You get what you pay for!! When using quality component speakers, make sure you're driving them with a quality amp. Using these with Polk MM series 6.5"s and an OEM center, so I am using 5 of the 6 available channels. It sounds fantastic and gets louder than I can tolerate without any distortion whatsoever. I am by no means an audiophile, but this was a worthy matchup for my Polks

Love this amp

August 19, 2012

I have this amp driving my factory setup (aftermarket components). 4-6x8s, and an 8-inch sub. The clarity is more than you can ask for no distortion at all. The HP/LP crossover is great for the speakers and sub combo and it makes the system sound great. Didn't have to sacrifice any space which was a big plus for me.

A tiny suprise!

March 8, 2012

Installed this in my VW Quantum/Passat, with a JBL component speaker set and a Pioneer 12" sub, and an Alpine headunit. The sound is so crisp and clear, and the amp has enough power for most uses. It is so compact, and gives so much bang for the buck, that i would advise anyone who is looking for a small powerful amp to power a complete moderate car stereo, to consider it! JL Quality!

Awesome sound, and performance!

May 2, 2011

Put one of these in my 325i Wagon BMW and never looked back. Great product specs, sound, and power. Active cross-overs work well with my mix of after-market speaker components, and the sub-out drives a couple of 6x9's to pound just enough bottom without sacrificing an inch of space. Runs cool and clean - love the sound. Quite frankly, I'm considering adding the 4x JL class D as well... SonicElectronix was my vendor of choice, and they delivered.

Superb sound you have to hear it to beleive it

October 3, 2010

Well, there's so much to say about this magnificent and fine piece of amp. The first thing to say about it begins with its crystal clear sound, this amp is driven by an 10 years old pioneer car stereo cd player. Yes I'm renewing the fleet on my car, and since the first try I noticed a huge difference from the previous amp from Pioneer that this amp was about to replace. I used 5 of the 6 channels that this baby comes with, 4 channels are connected to a set of 6x9" 160watts MB Quart speakers, the other channels drives an 12" Cerwin Vega single coil bass. So, I began the testing by playing a song from Enigma called "Sadness" the sounds from this song is a challenge to any sound system due to the deepness of the bass and the crisp of the highs. Well, all I can say is that never knew that the Cerwin Vega bass sounded so loud and deep since now. No distortion whatsoever, even with volume at 90%!!! The sound is just immaculate, crystal clear on the speakers as well in the bass. Every sound is perfect and bass is loud and the deepness of it is simply unbelievable. The size of this amp is another plus, in my case I placed it where is supposed to be the factory installed amp and it fitted so well that it looks like the OEM. Really easy to set up and adjust since every channel has it on crossover you can adjust the frequency range for every set of speakers. By doing this the distortion level on high volume can be eliminated and the efficiency and frequency response of the speakers is maximized. CONS: Lack of bolts and nuts to attach it to the vehicle's body the only hardware that comes with it is the Allen wrench to tight and release the screws for the wiring connections. So, a Home Depot visit is necessary to get 4 cylindrical head Allen screws with its bolts and washers in order to attach it to the vehicle. My impression for this amp is that if you are looking for something that can fit even under you seat and at the same time can literally blow off you hears and can afford it JUST GET IT !!! it worth the money.
