JL Audio's M600/6 marine amp is small — less than 11" wide — but it delivers a massive amount of power from its compact chassis — up to 100 watts from each of its six 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 6-channel amp for a variety of applications. Run three sets of high-performance coaxial or component speakers, or bridge the amp to 2-channel mode to get three subs thumping. Or enjoy the best of both worlds by powering a combination of full-range speakers and subs.
You can run the built-in variable frequency filters in high- or low-pass mode, depending on whether you're powering speakers or subs. JL Audio's optional wired remote lets you adjust the amp's level from the helm. 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.

Great style and sleek profile. Mounted great and looks good. JL is the way to go.
Small perfet size!!!
Running 6 MX650 CCX speakers hooked up to the JL AUDIO M600/6 amp, The MX10IB3 subwoofer is hooked up to the JL AUDIO M200/2 amp, all backed by the Clarion M505 head unit. This complete system ROCKS clarity, highs, mids, lows, and outstanding vocals. Put this in and you will be the envy of anyone listening.
Pros: Quality built product, lives up to the name for marine use.
Cons: Zero, none, if you have one it will be you pay for what you get. Quality
I am running this with 3 pair of M650s and a JL slash 500/1 with 2 10w5IBs. Initial disappointment is that the amp will not turn on with less than 12v at the remote turn on terminal. My Rockford Fosgate marine head unit only puts out 5v making the remote turn on useless without installing another relay which makes for a hassle and a messy install. The vintage JL amp powered up fine with 5v. Quite a lot of hiss from the speakers even with no signal being sent if gain is turned at all past 50% which is unexpected at this price point. I am running this off of an isolated, dedicated optima blue top running only the stereo, so noise is not from interference, alternator etc. That said, on a boat you don't notice the noise as much as in a car, but it is definitely noticeable inside the cabin.
Pros: Many channels, good controls, compact size
Cons: Price exceeds quality, not made in America anymore, may not turn on with your head units remote turn on wide
we purchased this amp for our pontoon boat. its powering a 10" jl sub plus 4 speakers. it packs a good punch. definitely can notice a difference.
Pros: good sound
Replaced an old 4 CH 600W amp that blew a channel. The crisp and clean sound that this amp provides is amazing! Yesterday is the first time I took my boat out and was able to really turn up my system, my wife and I both immediately noticed how much louder and cleaner the sound was coming from our tower speakers (6 Polk Audio 6x9's).
Pros: Compact size, availability of setup options, adjustability, power, clarity of sound.
Lots of clean power. Driven 3 pairs of Alpine speakers and they sound great!!!
Pros: Compact size, lots of power and different options to set up your system!
Cons: None at all!
Amazing amp! Powering 4 m650's and a IB 10" sub in my bow ride searay !
Pros: Power! Clarity! Compact size!
JL made a great amp with this one. I had no problem with my ability to hook it up and set it so it sounds good. Its small enough to almost mount it anywhere.
Pros: Small footprint, easy to set up,
I really like the compact design and flexibility of this amplifier. It has a good sound and plenty of power.

6-Channel Full-Range Amplifier: The JL Audio M600/6 is a six-channel, Class-D marine amplifier utilizing NexD ultra-high speed switching technology to deliver outstanding fidelity and efficiency. The M600/6 can be operated with a wide variety of source units and system configuration.
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 M600/6 Class D marine amplifier is rated at 75 Watts RMS x 6-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 three speaker wire-to-RCA adapters (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 M600/6 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 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 (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).
Note: The M600/6 is equipped with a independent gain controls for channels 1&2, 3&4, and 5&6.
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 M600/6 offers the following independent crossover adjustments for the front, rear, and subwoofer channels 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 50-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 50-amps, the original should be replaced with a 50-amp fuse.
Speaker Output Terminals: The M600/6 amplifier's twelve 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 3 sets of differential-balanced RCA jack inputs. The amplifier features a dedicated Input Sensitivity gain control for the front 1&2, 3&4, and 5&6 channels of the amplifier. These controls are designed to match the input sensitivity of the M600/6 to the specific signal source that is feeding it. The amplifier's input level can be set independently for the front and rear channels between 100mV-4V.
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 2, 4, or 6 channels of the M600/6 from 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 the rear side of the amplifier to make installation of the amplifier simple and neat.
