We consider it our mission to use our expertise in developing the latest technologies and to bring you the absolute best sounding amplifiers on the market at a reasonable price. From its clean, sleek design to its high-quality components, you will be amazed at the quality and power that these new Phenom amps offer. Before we talk about the actual amplifier, I wanted to point out that we included a microphone. Most brands do not do this. We wanted to provide you guys with the best sounding marine amplifier of course. But we also wanted to give you the ability to have a microphone so you can use all the power of the system to communicate when out on the water. This will give you many new applications of what you can use your marine system for. We included a special circuitry in the amplifier that when you talk through the microphone the music will get lower and when you are done talking the music will go back to normal volume. The RXM-F3 is a 4 channel amplifier with 1,600 Watts peak output and 65 Watts Dyno Certified RMS power @4 Ohms and 1% THD+N. You can also bridge the amplifier and get 2 x 200 Watts RMS @ 4Ohms. The Dyno Certified RMS Power Ratings is 65 x 4 @ 4 Ohms and 95 x 4 @ 2 ohms
