About this product
The NVY-IPX7.4 is a 4-channel Class D car amplifier from the DS18 NVY series, the brand's high-performance line. It delivers 4 x 120 watts at 4 ohms and 4 x 200 watts at 2 ohms RMS, or 2 x 350 watts bridged at 4 ohms, with 1440 watts total peak output. An IPX7 waterproof rating, with UV, salt and fog protection makes it suitable for boats, side-by-sides and powersports vehicles where the amplifier is exposed to water and spray. Signal-to-noise ratio is rated at greater than 90dB with total harmonic distortion of less than 0.1% across a 20Hz-20KHz response. A selectable HPF/FULL/LPF crossover covers 50Hz-4KHz. Wiring uses 8Ga power terminals and a 2 x 30A fuse, not included. Match the amplifier to the RMS rating of your speakers and set the gain to that rating for clean, reliable output.

IPX7 MARINE-GRADE BUILD
IPX7 waterproof rating and UV, salt and fog protection protect the amplifier on boats, side-by-sides and powersports vehicles, housed in a black / anodizing chassis. Built for installs where a standard car amplifier would not survive.
CLEAN SIGNAL PATH
Signal-to-noise ratio of greater than 90dB with total harmonic distortion of less than 0.1%, across a 20Hz-20KHz response. The amplifier reproduces the signal it is given instead of adding noise of its own.

A selectable HPF/FULL/LPF crossover covering 50Hz-4KHz. Send each channel only the frequencies it should reproduce without adding an external processor.
PROTECTION CIRCUITRY
Built with thermal, over-load, short circuit output and voltage input protection, so the amplifier shuts itself down before a wiring fault, a short or overheating can damage it or your speakers.
