About Rockville Quality Control Procedures:

The Rockville brand stands for Quality, Innovation and Value. All Rockville products go through the most rigorous quality control standards in the industry. Products go through months of extensive testing before they reach your hands. All user functions are tested and all internal components are tested for quality. Rockville makes products that are virtually un-breakable! Rockville is one of the only brands in its class to test every concept model for weeks or months before starting production. Once production begins, Rockville sends product engineers to their factory to quality control every line of production. During production every product is tested and on top of that Rockville goes the extra mile and has their high level product engineers do an additional quality control. They test a certain percentage of all products from the production line a second time to ensure that the quality meets their vigorous standards, and to make sure that there is never a batch of products with even a slight problem. All Rockville products are backed with a hassle free warranty.

Unboxing Video of RMWK4:

Rockville's exclusive Professional Marine Installation Kit features top of the line accessories which have been specifically engineered to withstand the toughest of marine environments. You will hear the difference and we guarantee you will not be disappointed! 

Rockville Marine Audio Interconnect cables are specifically engineered to withstand the challenges of both salt water and fresh water marine installations. The utilization of tinned Oxygen Free 100% copper conductors with polyethylene dielectrics in a twisted-pair arrangement optimizes noise rejection. The small-diameter white PVC jacket is ultra-flexible enabling our cables to be easily routed around bends and through tight spaces. Our exclusive molded connector features a water proof inner cap that is heat shrunk in place over all solder connections thus guaranteeing a completely water proof and corrosion resistant connection. The locking plug design with split pin technology further insures tight connections that will not vibrate free even during the most extreme boating maneuvers.

Our Marine Grade Speaker Cables are engineered for maximum signal transfer with minimum impedance loss. The cable strands are all individually tinned, fine-strand, oxygen-free copper with aluminum composite construction and provide a high-fidelity speaker connection that is especially engineered for the marine environment. Woven down to a flat shape, the cables can be easily routed throughout the bulkhead with ease. 

Rockville Marine Power Cables feature strands which are all individually tinned, fine-strand, oxygen-free copper with aluminum composite construction corrosion resistant and marine-ready. Fine-strand construction and soft PVC jacket deliver excellent flexibility. Our marine cables are much better quality than standard CCA wire kits. These kits have a very generous amount of copper in them. They are very similar in quality to the best brands kits on the market. The thickness of the wire is true-gauge. We have seen other brands who use thick plastic but very little copper inside the wire. Rockville wires are honest, true-to-spec and will make your music sound great.

Features:

• Rockville RMWK4 4AWG Guage Waterproof Marine/Boat Amplifier Wire Installation Kit
• 25’ Translucent, Twisted Pair, High Quality, Tinned-CCA Flexible PVC RCA Cable

Description of KRYPTON MF4:

We took the sound of our Krypton car amps and we added top of the line marine grade parts so that they will last forever and withstand even the harshest conditions on the water.

We went a little overboard (no pun intended) to make this amp marine ready. 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!

The 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.

This 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.

The 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.

You 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.

This is a class A/B amplifier which is what we recommend to get the best sound quality out of full range speakers.

One other cool features about this amp is the marine public address system. Simply plug the microphone into the 3.5mm jack and you are ready to go. The amplifier features talk-over functionality. When the microphone is being used the music will fade to the background until you stop talking into the mic
