Description
Description
This Nautic mono block amplifier brings marine-grade power to the water, with sealed and grommeted output connections plus an IPX-rated chassis that shrugs off spray and dust. Its full-range Class D design and FLUID-FET output devices deliver efficient power from a compact gloss white heat sink, while the top-mounted panel hides crossovers, bass boost and input sensitivity controls.
An included bass remote lets you tune the low end from the helm, and DC signal sense turns the amp on automatically through the RCA inputs so no remote turn-on wire is needed. Variable low-pass crossover runs 50Hz–250Hz, with 0–12dB bass boost and a selectable subsonic filter.
