Product Details

The MRDF-4 is a four-channel marine amplifier delivering 700W RMS total at a 2-ohm load for boat audio systems that need clear, full-range sound. Its Class D topology and compact format suit installations where cabin or console space is limited. At 2 ohms, it supplies 175W RMS per channel; at 4 ohms, it supplies 115W RMS per channel, or 350W RMS x 2 when bridged at 4 ohms. Adjustable high-pass and low-pass filters from 50Hz to 250Hz help tune full-range speakers, component speakers, or bridged subwoofers. White silicone terminal covers, sealed connections, a conformal-coated circuit board, stainless steel hardware, and a UV- and salt-resistant chassis are built for marine conditions. Power, status-mode, and clipping indicators provide at-a-glance operating feedback. The package includes the amplifier, terminal covers, mounting hardware, and spare fuses.

Features

    • Marine-Sealed Connections

      White silicone covers seal around power, ground, remote, and RCA connections, helping shield these points from splashes and salt corrosion aboard the boat.

    • Protection for Humid Conditions

      A conformal-coated circuit board and UV- and salt-resistant chassis shield internal electronics from moisture, salt air, and humidity during marine use.

    • Full-Range Output in a Small Footprint

      Micro-size Class D circuitry with SMD components and a high-speed MOSFET supply delivers 700W RMS total at 2 ohms in a compact chassis.

    • Tune for Your Speaker Setup

      Adjustable high-pass and low-pass filters cover 50Hz to 250Hz for shaping full-range speakers, component speakers, or bridged subwoofers in a boat audio system.

    • Check Operating Status at a Glance

      Power, status-mode, and clipping LEDs report amplifier conditions, while thermal, short-circuit, and over-voltage protection guard against common operating faults during operation.
