Power Acoustik went the extra mile to make these amplifiers marinized grade. They were built from the ground up to be the finest possible amp for your off-road vehicles, motorcycles, or personal watercraft.

Made splash-and-spray-resistant conformal coated circuit boards and terminals, It’s all engineered to maintain top-shelf performance for years to come.

We’ve engineered traditional Razor amplifiers to fit in virtually any location in your ride. Other sport compact amplifiers use bizarre technologies with pseudo power supplies, FAKE NEWS! Razor amps use tried and tested MOSFET power supplies & tenacious Class-D circuitry.

Are you using an original or factory radio? No problem, these amplifiers are equipped with an Automatic Hi-Level Signal Sensing Turn-On. There is no need to run a remote wire turn on; this amplifier will automatically detect the sound signal and turn on and off the amplifier. (Hi-Level Input only)
