JL Audio's XD300/1v2 amp packs a wallop far beyond what you'd expect from something so small. This amp plays bass with true fidelity and impressive impact, without straining your car's electrical system. A cast alloy heatsink and an advanced cooling system keep this amp at optimal temperature, eliminating thermal shut-downs so your music keeps going strong without interruption.
The XD300/1v2 mono amp delivers up to 300 watts RMS to your subwoofer, and its low-pass filter features a choice of slopes for better control over the character of your bass. A subsonic filter allows you to tighten up your system's kick and gets rid of any inaudible, low-frequency information that could detract from your sub's performance.
"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. The speaker-level inputs feature two auto turn-on modes so you can readily incorporate this amp into a factory system — no need for RCA connections or a remote turn-on lead. An optional wired remote lets you tweak the volume of your sub from the front seat.

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.
I have always been a fan of JL Audio but never owed anything. Bought this along with a JL 12in sub! Awesome power and it stays super cool!!!! A must buy if you want a great amp that even though it is small. It packs a huge hit and great sound quality!
Wonderful amp with jl 13w3 v2 with pioneer radio and hertz deice all the way around make for the complete setup
Installation is a breeze thanks to the clamp-style connectors that take bare wire and speaker-level or pre-amo inputs. This amp is made for bass, evident by the low-end specific crossover/filter functions which are simple and easy to adjust. This little amp has a lot of power inside - I have my XD300/1v2 powering a pair of 10" Kicker subwoofers at 2-ohms and after 20 minutes continuous high output, the amp heatsink is slightly warm, but nowhere near hot. The alloy faceplate that covers the controls is a nice touch. You can also opt for the HD-RLC remote level knob to control bass output from the front seat, but it costs extra. Finally, don't be surprised if you open the box and find that the XD300/1v2 is a lot smaller than expected - it is built solid and I'm happy to say that its performance is worthy of the 5-star rating.
Pros: Lots of power Small footprint Connector-free installation
Cons: Remote level control is optional

XDv2 Series: The JL Audio XDv2 amplifiers feature big audio performance from a small footprint. With advanced NexD switching technologies, the XDv2 amps exceed 80% efficiency, running cooler than most other amplifiers. The Advanced Thermal Rollback System gives you increased reliability and better audio performance by virtually eliminating thermal shut-down. Because the XDv2 amps employ smaller cast alloy heat sinks, they can be installed in smaller spaces. XDv2 amplifiers feature a black powder-coat finish with a brushed aluminum cover for the controls.
Monoblock Class-D Subwoofer Amplifier: The XD300/1v2 is a Class-D monoblock amplifier, designed specifically for driving subwoofers. It has two positive and two negative speaker output connections to make it easier to connect multiple subwoofers. The terminals are wired in parallel internally. The amplifier is stable down to 2 ohms.
Amplifier Rating: The XD300/1v2 is rated at 200 Watts RMS x 1 channel at 4-ohms (20 Hz to 20 kHz), Signal-to-Noise Ratio of >100 dB, 1% THD, @14.4 Volts. At 3 ohms, the rated power is 250 Watts RMS, and at 2 ohms, it outputs 300 Watts RMS.
Advanced Rollback Protection: The XDv2-Series amplifiers employ advanced thermal and low-impedance protection to virtually eliminate annoying amplifier shut-down events. Should any XDv2-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 XDv2 amplifier will roll back peak voltage to protect itself without shutting down.
Differential-Balanced Inputs: The XD300/1v2 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 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 adapter (sold separately) to connect this amplifier to your head unit 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.
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 XD300/1v2 features a brushed aluminum 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 to access the amplifier's controls. The security cover is secured by two 2.5mm hex-head screws.
Simplified Gain Setting: This XDv2 Series amplifier makes setting the gain level of the amp via the input sensitivity control very simple. All you need is Digital AC Voltmeter and a CD Test Disc 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 subwoofers).
Flexible Input Section And Active Crossover Network: The XD300/1v2 amplifier provides a flexible input section and a comprehensive crossover network to fine tune your system effectively and accurately:
Turn-on Options: The Turn-on Mode Switch lets you choose the method for turning the amplifier on and off:
Note: When the DC Offset or Signal Sensing turn-on methods are being used, the amp's Remote terminal can be used as a remote turn-on output for other amplifiers or accessories in the system.
Power/Ground/Turn-On Terminals: This JL Audio XDv2 amplifier features set screw clamp terminals for the power, ground, and remote turn-on connections. A 2.5mm hex-wrench is supplied for tightening or loosening the set screws.
Note: The Amplifier is not equipped with a fuse. An external 30-amp AFS, AGU, or MAXI fuse must be installed on the power wire. If a wiring kit is used which includes a fuse with a value other than 30-amps, the original should be replaced with a 30-amp fuse.
Speaker Output Terminals: The JL Audio XD300/1v2 features four set screw clamp speaker terminals for an easy parallel subwoofer connection. The terminals will accept 16 to 8 AWG speaker wire.
Preamp Inputs: The amplifier features one set of differential-balanced RCA jack inputs with an Input Voltage switch. For preamp level signals, the switch should be set to LOW. For speaker level signals, the switch should be set to HIGH. The rotary Input Sensitivity gain control can be set the amp to the specific signal source that is feeding it. The amplifier's input voltage range is 200mV-2V (LOW) and 800mV-8V (HIGH).
Preamp Outputs: The XD300/1v2 incorporates a buffered pass-through preamp output section, so that additional amplifiers can be easily added to the system. The preamp output signal is not affected by the amp's Low-Pass Filter. If the Input Voltage switch is in the LOW position, the level of the Preouts matches the input signal strength. When the Input Voltage switch is in the HIGH position, the level of the input signal is attenuated -12dB to produce a line-level signal at the Preouts.
Remote Level Control: The amplifier features a standard RJ-14 telephone connector for adding the optional wired HD-RLC Remote Level Control (sold separately). The Remote Level Control lets you control the volume of the XD300/1v2 from the driver's seat.
