Know before you buy
An IPX7 rating means this amplifier is fully submersible in water up to one meter deep for up to 30 minutes. It is designed to withstand direct water exposure, making it ideal for boats, jet skis, and off-road vehicles where moisture is a constant factor.
Yes, the NVY-IPX7.4 is bridgeable, allowing you to combine channels to drive a subwoofer. With 120W RMS per channel at 4 ohms, it provides enough power for most standard marine subwoofer setups.
Absolutely. Beyond its waterproof rating, the chassis is sealed against salt fog and UV rays, which are common causes of corrosion in outdoor environments. Its compact size also makes it easy to tuck away in tight spaces on a UTV or motorcycle.
Class D amplifiers are highly efficient, meaning they convert more power into sound rather than heat. This puts less strain on your vehicle's electrical system compared to older amplifier designs, which is crucial for marine and powersports applications with limited battery capacity.
The amplifier features variable gain and crossover controls that can be adjusted with a standard flat-head screwdriver. These controls allow you to fine-tune your audio output to match your specific speakers and listening preferences.
The unit measures 10 inches long, 4.5 inches wide, and 1.9 inches high. Its slim, compact footprint is specifically engineered to fit into the cramped mounting locations often found in powersports vehicles and marine consoles.
