Skar Audio engineered the RP-800.1D Class D monoblock subwoofer amplifier to be dominant in both power and reliability compared to anything else on the market in 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-800.1D.
The RP-800.1D 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 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 by far one of the most popular and affordable mono-blocks we have ever released, and is great for powering a "daily driver" subwoofer stage in any vehicle.
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.
