Each JL Audio XD amp packs a wallop far beyond what you'd expect from something so small. This super-compact amp plays your music with true fidelity and impressive impact, without straining your car's electrical system. A cast alloy heatsink and an advanced cooling system keep these amps at optimal temperature, eliminating thermal shut-downs so your music keeps going strong without interruption.
The JL Audio XD200/2 2-channel amp can deliver 75 watts RMS per channel to a pair of speakers. You can also bridge this amp to 1-channel mode to power a sub with 200 watts. High- and low-pass filters give you intimate control over the character of your sound.
This amp is a great choice for powering a sound system on your motorcycle or ATV because its compact size allows for more mounting options, and its unregulated power supply draws very little energy from your electrical system. "Differential-balanced" inputs keep the signals clear of outside noise, and allow you to connect this amp to just about any in-dash stereo, even a factory radio with no preamp outputs. An optional wired remote lets you tweak the level from your front seat.

My system has plenty of power. Who needs an amp?
You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.
JL Audio XD200/2 Reviews
Average Customer Review:
Awesome as usual
Crutchfield Customer Review (What's this?)
JL Audio has never disappointed me. Just reliable, well-thought through, well-made stuff. This little amp is no exception. I ordered it along with the JL Audio CL-RLC, which I'm using as an active volume pot. I opted to not install a CD player since seriously who listens to CD's anymore? I just plug my smartphone into the CL-RLC via a panel-mounted 3.5MM jack, turn on the tunes, and control the volume with the volume knob from the CL-RLC. It runs through this little 2 channel amp, which is great for my Jeep since I only use a front stage anyway.
Pros: Teeny tiny! Fits in the smallest spaces. Easy instructions for setting the gains with a voltmeter. I love it.
Cons: None yet, but I don't anticipate any.
Good things come in small packages
Crutchfield Customer Review (What's this?)
This JL amp is pretty amazing. If 75w x 2 is sufficient for your components, this is the amp to go with, especially if you are interfacing with an OEM system that uses balanced differential inputs.
Pros: Very small Differential balanced inputs Clean power JL build quality RCA passthrough
Cons: A little pricier than other amps - but you get what you pay for Aluminum finishing panel must be removed via allen wrench to access gain/xover adjustments
Crutchfield Customer Review (What's this?)
This amp sounds great. It powers my rear speakers and is a very noticeable improvement
over the aftermarket head unit amp. My amp for the front speakers is a McIntosh, and this
little JL is practically it's equal in quality. The build quality is superb. I would recommend any
XD amp to power your system; just phenomenal sound. This is my first JL experience and if I
had to start over, I would feel comfortable having all JL gear (the amp is powering new 6" JL
coaxial's that sound beautiful). I had to exchange a bigger JL amp that didn't fit under my
seat for this one and Crutchfield's customer service was perfect. Thanks.

2-Channel Full-Range Amplifier: The JL Audio XD200/2 is a two-channel, full-range audio amplifier utilizing NexD ultra-high speed switching technology to deliver outstanding fidelity and efficiency. The XD200/2 can be operated with a wide variety of source units and system configurations.
Amplifier Rating: The JL Audio XD200/2 Class D two-channel amplifier is rated at 75 Watts RMS x 2-channels in 4-ohm at 20 to 20,000Hz with a signal-to-noise-ratio of 104 dB and a total harmonic distortion of 1% while receiving 14.4 Volts.
NexD Class D Technology: NexD is a state-of-the-art switching amplifier design that combines exceptional audio quality with excellent efficiency and less complexity. This results in an affordable compact amplification with exceptional audio quality and unsurpassed total efficiency.
Advanced Rollback Protection: The XD-Series amplifiers employ advanced thermal and low-impedance protection to virtually eliminate annoying amplifier shut-down events. Should any XD-Series amplifier ever overheat, its intelligent, unregulated power supply reacts by limiting available peak voltage until the amplifier returns to a safe temperature range. Likewise, if an impedance lower than optimal for the amplifier is present at the outputs, the XD amplifier will roll back peak voltage to protect itself without shutting down.
Differential-Balanced Inputs: The JL Audio amplifier features differential-balanced input architecture to effectively control noise and ensure compatibility with a wide variety of source units, including many OEM systems. Without resorting to line output converters, you can directly connect most OEM source units to the JL Audio amplifier without creating any noise or compatibility issues. Unlike conventional single-ended inputs, the differential-balanced design does not connect one side of the audio signal to chassis ground. This eliminates any voltage sensitivity between one input terminal and ground and greatly reduces the incidence of alternator whine in a typical car audio installation.
Note: You will need a speaker wire to RCA adaptor (136XDCLR2S, sold separately) to connect this amplifier to your headunit via speaker-level.
Protection Circuitry With Status Indicator Lights: There is a single multi-color LED on the top panel of the amplifier to indicate the amplifier's operating status.
- Flashing Green: When the LED is flashing green, the amplifier is powering up and audio output is muted.
- Constant Green: This LED lights green to indicate that the amplifier is turned on and operating normally.
- Constant Red: This Red LED lights to indicate that the amplifier has exceeded its safe operating temperature, putting the amplifier into a self-protection mode, which reduces the power output of the amplifier. The red light will shut off and the amplifier will return to normal, full-power operating mode if the heat sink temperature drops back to a safe level.
- Constant Amber (Yellow): The Amber (Yellow) LED light indicates that an over-current condition has occurred and is accompanied by a muting of the amplifier's output. Over-current condition can be caused by a speaker impedance lower than the optimum load impedance range for the amplifier or a short-circuit in the speaker wiring.
- LED Off: The only condition that will shut down an undamaged XD200/2 completely is if battery voltage or remote turn-on voltage drops below 10-volts. The amplifier will turn back on when voltage climbs back above 11-volts.
Cooling System: The outer shell of the JL Audio amplifier is designed to remove heat from the amplifier circuitry. For optimum cooling performance, this outer shell should be exposed to as large a volume of air as possible. Enclosing the amplifier in a small, poorly ventilated chamber can lead to excessive heat build-up and degraded performance.
Control Panel Cover: The XD200/2 features a Control Panel Security Cover which protects and hides the amplifier's controls. When installed, the cover ensures that the amplifier's settings are not accidentally changed while creating a clean aesthetic look for the amplifier and your installation. The control panel security cover is pre-installed at the factory and must be temporarily removed for access the amplifier's controls. The security cover is secured by two 2.5mm hex-head screws.
Simplified Gain Setting: The XD Series amplifier makes setting the gain level of the amp via the input sensitivity control very simple. All you need is Digital AC Voltmeter (142TK12V, sold separately) and a Test CD Disc (503CD104, sold separately) with a sine-wave test-tone recorded at 0 dB reference level in the frequency range to be amplified for that set of channels (50 Hz for subwoofer channels, 1 kHz for a midrange application).
Flexible Input Section And Active Crossover Network: The JL Audio XD amplifier provides a flexible input section and a comprehensive crossover network to fine tune your system effectively and accurately. The variable filter design employed in the JL Audio XD amplifier crossover sections allow you to seamlessly switch slopes, easily change filter frequencies and address what frequencies the preamp inputs will pass. The XD200/2 offers the following crossover adjustments along the unit's top panel, behind a removal cover plate.
- Filter Mode: The amplifier allows you to select either a Low Pass, High Pass or Full-Range operation.
- Variable Frequency: You can set the amplifier's Low Pass or High Pass crossover from 50 to 500 Hz.
Power/Ground/Turn-On Terminals: The amplifier features set-screw terminals for the power, ground, and remote turn-on connections.
- Power and Ground: The JL Audio amplifier's set-screw Power and Ground connections are designed to accept 8 to 4 AWG power wire. A 2.5mm hex-wrench is supplied for making connections.
- Remote Turn-On: The JL Audio XD amplifier's set-screw turn-on lead will accept 18 to 8 AWG wire. The same 2.5mm hex-wrench is supplied for making connection.
Note: The Amplifier is not equipped with a fuse. An external 20-amp AFS, AGU, or MAXI fuse (not included) must be installed on the power wire. If a wiring kit is used which includes a fuse with a value other than 20-amps, the original should be replaced with a 20-amp fuse
Speaker Output Terminals: The XD200/2 amplifier's four set-screw speaker terminals will accept 16 to 8 AWG speaker wire. A 2.5mm hex-wrench is supplied for making connections.
Preamp Inputs: The amplifier features one pair of differential-balanced RCA jack inputs. The amplifier features an Input Sensitivity gain control. These controls are designed to match the input sensitivity of the XD200/2 to the specific signal source that is feeding it. The amplifier's input level can be set between 100mV-4V.
Preamp Outputs: The XD200/2 incorporates a pass-through preamp output section, so that additional amplifiers can easily be connected to the same signal(s) feeding the XD200/2. These preamp output signals are buffered to prevent noise and are always preamp level, regardless of the level of signals feeding the XD200/2's inputs.
Remote Level Control: The amplifier features a standard telephone connector for adding an optional wired remote level control. With the addition of the optional wired Remote Level Control (136HDRLC, sold separately), you can control the volume of the XD200/2 form the front of your vehicle. This is useful for subwoofer level control or even as a master volume control for your system. If desired, multiple XD amplifiers can be controlled from a single HD-RLC controller using a simple phone line splitter and multiple phone cables (all sold separately).
Note: All inputs and outputs are located on one side of the amplifier to make installation of the amplifier simple and neat.
