Skar Audio engineered the RP-800.1DM marine amplifier to be unrivaled in both performance and reliability compared to anything else on the marine market its class. Designing the most efficient, well built, high quality amplifiers is where we start here at Skar Audio, and that is exactly what is delivered in the RP-800.1DM.
The RP-800.1DM is 1-ohm stable and utilizes a wide array premium internal components that make it extremely powerful and reliable - such as its high speed MOSFET power supply and advanced, marine grade, PCB board layout. Conservatively rated at 800 watts RMS power at a 1-ohm load, with the capabilities of reaching beyond 1,200 watts at max power output, this amplifier is great for powering the sub stage on your boat/UTV.
Furthermore, the oversized 4-gauge power and ground terminals found on the amplifier allow for maximum current flow and therefore higher power output and more efficient operation. You'll have full reign over your amplifier with the built-in user control panel, featuring a bass EQ switch (0, +6, +12dB), and variable adjustment tunings for gain level, low-pass filter, and subsonic filter.
In addition to all the above features, this model also features 4-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. This amplifier comes with a remote subwoofer level control (bass knob) allowing the user to have full control over their bass from anywhere on the watercraft.
