Skar Audio engineered the RP-75.4ABM marine amplifier to set a new standard in marine grade amplifier performance. This four-channel marine amplifier is 2-ohm stable and utilizes a wide array of premium internal components, such as its high speed MOSFET power supply as well as an advanced marine grade PCB board layout. Conservatively rated at 500 watts RMS power (125 watts x 4 channels), this amplifier will bring the speakers on your boat to life with unrivaled power output and sound clarity.
The RP-75.4ABM is extremely versatile as well with its compact physical design, which allows it to fit in a variety of tight or small locations on your boat. Also present on one side of the amplifier is a built-in user control panel that is fully adjustable - allowing you to dial in your sound exactly how you want it. Featuring adjustable controls for gain, high pass filter, low pass filter, a crossover switch, and more, you'll have full control over your listening experience.
In addition to all the above features, this model also features four-way protection circuitry, which will give the user the peace of mind knowing they are protected against damage to the amplifier for various reasons - including electrical shortage, overheating, low voltage, and more. Our marine amplifiers feature a special marine coating internally that allow them to withstand the harshest conditions for long lasting use.

Although this amp is the best bang for your buck i believe the control panel could have some revising as the amp is stated to be a marine amp it can t even take a light mist when washing down the sxs. I have it mounted to the roof un enclosed so it can breath and there s no way of being submerged the controls got wet when washing down and put the amp into protection mode. Only way to get it to work again was by putting a heater on it to dry the components out. Good amp for the money but needs revising if your going to consider it marine
