Rockford Fosgate M2 4 Channel Marine Amp
The Rockford Fosgate M2-300X4 is one of the best values for a 4 channel marine amplifier. The M2 300 watt amplifier delivers 70 watts RMS per channel
and is a perfect match for most 6.5" marine speakers. We love this amp to power a pair of Rockford Fosgate M1 6.5" speakers, JL Audio M3 6.5" speakers, and most other mid-level options.
This amplifier uses Class-D circuitry for maximum efficiency with minimal current draw. This means your amp still delivers the power your speakers need, but with minimal impact on your boat's charging system. This amp should be able to run all day long without having to worry about it cutting out due to over heating.
LED Clipping Indicators
The Rockford Fosgate M2-300X4 features Rockford's C.L.E.A.N. setup technology. The LED clipping indicators allow you to set the gains at the optimal level. This ensures that you don't get a clipped signal input signal from your head unit
and you don't get an output clip from the the amplifier.
70W x 4 Actual Power Output
The M2-300X4 will outperform the 50W x 4 RMS power rating. Each amplifier comes with a birth certificate that will tell you the actual power output of the amplifier. With the M2-300X4, it will deliver 70 watts per channel in a real-world, listening-to-music scenario. Music is dynamic as you can see anytime you look at an equalizer. The dynamic rating represents what you can expect when listening to music, not just
testing things on a bench.
Efficient Class D Circuitry
The M2 series marine amps from Rockford Fosgate are their only lines that deliver true, Class-D circuitry. Technology has advanced and Class D amplifiers are ideal for the marine environment due to their efficiency
and minimal current draw, given the output. With the M2-300X4, you get a full-size amplifier, in a fairly compact chassis, that can handle long, hot days on the water with the stereo playing all day long. In addition, the efficiency is nice if you listen to your stereo while the engines are turned off. The efficient Class D circuitry will play longer than a Class AB amplifier.
