Monoblock Class D Full-Range Marine Amplifier, 300 W x 1 @ 2 Ω / 160 W x 1 @ 4 Ω - 14.4V Engineered specifically for limited-space marine applications, the MHX300/1 monoblock amplifier employs our high-speed NexD™ switching design to pack a serious punch, while still being kind to small charging systems. Its ultra-compact, cast aluminum chassis is highly resistant to corrosion, with an IPX6 water-resistance rating, making it ideal for applications where moisture would prohibit use of a conventional 12V amplifier. Producing a robust 300W of clean power into a 2-ohm load (14.4V, 1% THD), the MHX300/1 full-range, monoblock amplifier can be used alone or in stereo pairs. Use one to drive a subwoofer, or grab a pair to deliver stunning output to a subwoofer system or full-range satellites. Onboard controls include an adjustable low-pass crossover, a bass boost EQ, variable infrasonic filter and output polarity switch. Its dual-range input section accepts a wide range of input voltage levels, from line-level all the way to high-power speaker level signals. With the addition of an M-RBC-1 remote level control (sold separately), subwoofer output can be directly controlled from the driver’s seat. This marine amplifier features a white powder-coated finish, a gasketed cover for the controls and stainless steel hardware for durability in the marine environment.
