Rockford Fosgate's compact marine amplifiers provide high-efficiency Class-D power for your marine audio system. They meet tough UV and Salt-Fog protection standards, so you can install them with confidence in your pleasure craft, whether you're blasting across inland waterways, or cruising out to your favorite salt-water fishing grounds.
The M600-D4 4-channel amp delivers the power you need to drive two pairs of full-range speakers in your boat, sending 100 watts continuous power to each speaker. If you want to power a pair of subs, you can bridge the amp to 2-channel mode, sending 300 watts to each subwoofer — plenty of kick if you want some bass on board.
The amp features variable frequency filters to adjust the amp's output to your system, whether you're running full-range speakers or subs. And the compact footprint makes it easy to mount the amp in a small storage locker or other tight spot.
Love this amp, very impressive, replaced my old one, man what a difference!
Pros: Easy enough to hook up, everything clearly mark. Nice size ( smaller than my previous one ), It nice to have the extra power.
Cons: Probably only a con to me, I mounted this on the inside of my center console, I can only put the thur bolts in from one direction.
A great Amp in my Kawasaki Teryx 750 Loud and clear sound. A great amp. Thank you Crutchfield.
Pros: Great, Loud, clear and weatherproof
Amazing sound. Quality connections. Couldn't be happier.
Pros: Everything about it. Sleek, loud, this is perfect.
Great amp! I've tried a lot of brands and I think Rockford Fosgate makes the best boat amp around. Plenty of clean power, no noise, and that base boost pumps. I paired with Polk ultra marine speaker 4 x 100w and they sound great together. Don't even need to add a sub.
Pros: Good clean power. No noise. Compact size for power rating.

Overview: The Rockford Fosgate Prime Marine M600-4D is a 4-channel full-range Class D marine amplifier. It is optimized to power a full-range front/rear speaker system. You can also bridge the front and/or rear channels to run a subwoofer or two. The Class D design is very efficient with a cast aluminum heatsink to keep it in a small footprint.
Marine Amplifier: The M600-4D is designed for the harsh marine environment. The amplifier features a conformal-coated PCB and UV-resistant finish, and conforms to UV and Salt-Fog protection standards.
CEA-2006 Compliant: CEA-2006 is a system of testing and measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for determining an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4-ohm load with 1% or less Total Harmonic Distortion plus noise (THD+N). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006 allows consumers to compare amplifiers and receivers on an equal basis. The CEA-2006-rated RMS power output is as follows (measured with a 14.4 volt input, <1% THD+N, 20 Hz-250 Hz):
LED Indicator: The amplifier is equipped with a top-mounted LED indicator which illuminates blue when the unit is turned on. The LED illuminates red when a protection circuit engages (short circuit or too low an impedance is detected at the speaker connections). The amplifier automatically turns off if this occurs.
Mounting: The amplifier can be mounted vertically, horizontally, or inverted using the supplied mounting screws; horizontal mounting (right side up) will provide the best cooling.
Independent Controls: The M600-4D has independent, top-mounted controls for the front and rear channels. The controls include:
Punch EQ: The rear channel has an independent Punch EQ (bass boost) control that works with the crossover switch. When the rear channel crossover is set to low-pass, the Punch EQ can add a bass boost, centered at 45 Hz, from 0 dB to +18 dB.
2/4 CH Switch: When the 2/4 CH switch is set to the 2 CH position, the inputs are switched to a 2-channel mode. The signal on the front input feeds all four output channels, however, you lose front to rear fading capability. In the 4 CH position, the amp uses both front and rear inputs and fading capability is restored.
Power Terminals: The power and ground terminals are nickel-plated set-screw terminals, and will accommodate up to 4-gauge wire. The set screws can be tightened/loosened with the supplied 3mm hex key.
Fuses: The amplifier does not have on-board fuses. A 60A fuse should be placed on the power wire within 18" of the battery.
Remote Turn-On Terminal: The remote turn-on terminal is a nickel-plated set-screw terminal that will accommodate up to 8-gauge wire. The set screws can be tightened/loosened with the supplied 3mm hex key.
Speaker Terminals: The speaker terminals are nickel-plated set-screw terminals that will accommodate up to 8-gauge wire. The set screws can be tightened/loosened with the supplied 3mm hex key.
RCA Input Jacks: There are two pairs of RCA input jacks for the front and rear channels. They are nickel-plated to resist signal degradation caused by corrosion.
RCA Pass-Thru Jacks: The nickel-plated RCA pass-thru jack provides a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of the vehicle to the amplifier location.
