KS-DR1004D Amplifier & N2-WBT Bluetooth Controller

This bundle pairs the JVC KS-DR1004D 400-watt 4-channel amplifier with the MB Quart N2-WBT, a Bluetooth source controller built to mount directly in a standard switch panel on a Polaris RZR, ATV, or UTV, replacing a head unit with a single weatherproof control point.

The KS-DR1004D drives your speakers with 400 watts of Class-D power across 4 channels, protected by conformal coating that resists moisture and salt spray. Variable HPF and LPF rotary controls let you dial in the crossover to your specific speaker setup.

The N2-WBT meets American Boat and Yacht Council and ASTM marine electronics standards, streaming music over Bluetooth or through a 3.5mm aux input from any phone or media player. A fingertip joystick handles play, pause, track skip, volume, and power, all sealed against the elements, and Bluetooth Connect pairs a phone in seconds without a complicated setup process. It outputs to the amplifier through a single pair of RCA connections at 2V, with a backlit display for use after dark, and mounts in a standard 0.83 x 1.41-inch switch hole at just 2.5 inches of mounting depth, fitting the same panel space as any other rocker switch on the dash.
