JL Audio's M200/2 marine amplifier is small — less than 7" wide — but it delivers a massive amount of power from its compact chassis — up to 100 watts from its two channels. It owes these impressive specs to JL Audio's Class D NexD™ ultra-high-speed switching design, which eliminates the traditional drawbacks of a Class D amp design to deliver full-bandwidth performance, excellent efficiency, and very low distortion levels.
You can use this 2-channel amp for a variety of applications. It's great for kicking up the power to a pair of high-performance coaxial or component speakers, or you can bridge the amp to a single channel to drive a sub. You can run the built-in variable frequency filters in high- or low-pass mode, depending on whether you're powering speakers or subs.
A set of preamp outputs makes it easier to get signal to another amplifier in your system. The special powder-coat finishes, the gasketed control cover, and the stainless-steel hardware all protect this amp against the harsh realities of the marine environment.
Average Customer Review(s):
Excellent Product !!!
Marine installation. Unit was straightforward to setup and install - small size is a big help. Mounted the amp in the interior cabin in a large closet. Too early to tell how reliable it will be - would be nice to have a review opportunity 12mo or so after it's installed. But the sound (driving a JBL MX10IB3-CH-WH 10" sub mounted topside) is great.

2-Channel Full-Range Amplifier: The JL Audio M200/2 is a two-channel, full-range audio marine amplifier utilizing NexD ultra-high speed switching technology to deliver outstanding fidelity and efficiency. The M200/2 can be operated with a wide variety of source units and system configurations.
Marine Amplifier: The JL Audio M-series marine amplifiers are specifically designed for marine applications. These amps are not waterproof, however, and should not be mounted where they are likely to get wet.
Amplifier Rating: The JL Audio M200/2 Class D two-channel marine 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 M-Series amplifiers employ advanced thermal and low-impedance protection to virtually eliminate annoying amplifier shut-down events. Should any M-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 M-series 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 12-volt 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.
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 M200/2 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 Allen-head screws.
Simplified Gain Setting: The M-Series amplifier makes setting the gain level of the amp via the input sensitivity control very simple. All you need is Digital AC Voltmeter (sold separately) and a Test CD Disc (also 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 M-series 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 M-series amplifier crossover sections allow you to seamlessly switch slopes, easily change filter frequencies and address what frequencies the preamp inputs will pass. The M200/2 offers the following crossover adjustments along the unit's top panel, behind a removal cover plate.
Power/Ground/Turn-On Terminals: The amplifier features set-screw terminals for the power, ground, and remote turn-on connections.
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 M200/2 amplifier's four set-screw speaker terminals will accept 16 to 8 AWG speaker wire. A 2.5mm Allen 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 M200/2 to the specific signal source that is feeding it. The amplifier's input level can be set between 100mV-4V.
Preamp Outputs: The M200/2 incorporates a pass-through preamp output section, so that additional amplifiers can easily be connected to the same signal(s) feeding the M200/2. These preamp output signals are buffered to prevent noise and are always preamp level, regardless of the level of signals feeding the M200/2'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 M200/2 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 M-series 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.
