Know before you buy
An IP67 rating means the amplifier is completely protected against dust and can withstand immersion in water up to one meter deep for 30 minutes. This makes it ideal for marine environments, ATVs, and UTVs where exposure to rain, splashes, or washdowns is common.
Yes, this is a 4-channel amplifier that supports bridging. When bridged, it operates at a minimum impedance of 4 ohms, allowing you to combine channels for higher power output to a single subwoofer or a pair of high-demand speakers.
With a low-profile design measuring 11.6" x 4.9" x 1.8", this unit is engineered for compact installation. Its small footprint and versatile mounting options make it easy to tuck away in consoles, under seats, or in other restricted areas.
It features a direct power harness and waterproof terminals to ensure signal integrity and protection against corrosion. While it simplifies the connection process, you should ensure your power and ground cables are sized appropriately for the 2400W peak output to maintain performance.
Yes, it is a full-range Class D amplifier with a frequency response of 20Hz-20KHz. It is designed to power a wide variety of marine or powersports speakers, providing clean, consistent audio across the entire audible spectrum.
Class D amplifiers are highly efficient, meaning they convert more power into sound and less into heat compared to traditional designs. This efficiency reduces the strain on your vehicle's battery and charging system, which is particularly important in marine and powersports applications.
