We conformal coated the PCB board with a waterproof glue that is painted on to protect the circuitry. The heat sink, including the bottom plate, is made of aluminum which is rustproof. The end panels, internal mounting screws and hardware of the amp are made of stainless steel and are rustproof. Even after many years of use the amp will be rust free and operate like new!\u003cbr\u003e\u003cbr\u003eThe KRYPTON MF4 is a class AB 4-Channel high power amplifier with 2,400 watts peak output and 600 watts Dyno certified RMS power. The peak rating can be used to compare with brands who use peak ratings such as Boss and Power Acoustik while the Dyno Certified RMS rating can be used to compare with top brands such as Kicker, Rockford, Alpine, etc.\u003cbr\u003e\u003cbr\u003eThis amp has a very cool fully adjustable 12dB\/Octave crossover. What is cool about it is that our crossover supports low pass, high pass, bandpass, and subsonic. This makes our amp ideal for subwoofers (sealed and vented), full range speakers, and midrange speakers. In high pass mode we allow you to filter out frequencies between 15Hz - 4K Hz. In full mode you will not be filtering any frequencies. The really cool part is in low pass mode you can use the high pass and low pass mode. So for example you can set the low pass mode to 50 hz, and then you can set the high pass to 15 Hz. In this case you would be playing frequencies in the range of 15-50 Hz on this channel. This would be an example of using the subsonic filter. Another option you have is for midrange speakers, you can use our low pass filter and set it really high. Lets say to 3Khz and then you can set the high pass to 150Hz and your midrange speakers will only play that frequency range. Our advanced crossover technology will allow you to really fine tune each speaker to get the sound you desire.\u003cbr\u003e\u003cbr\u003eThe KRYPTON MF4 is protected by a fully IC controlled circuit which includes mute, delay and soft start technology so that the amplifier will turn on safely every time and protect your speakers from popping.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-family: Arial; color: rgb(31, 73, 125);\"\u003eYou will also notice we decided to add a cool battery voltage display meter which looks great but also serves as a tool for you to know if your battery voltage is dropping which would affect your systems performance. We designed the amps to be able to last for many years even if you are playing them at max volume before clipping for extended periods of time.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-family: Arial; color: rgb(31, 73, 125);\"\u003eThis is a class A\/B amplifier which is what we recommend to get the best sound quality out of full range speakers.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-family: Arial; color: rgb(31, 73, 125);\"\u003eOne other cool features about this amp is the marine public address system.
