JL Audio XDM300/1 Mono Car & Marine Subwoofer Amplifier — 300 watts RMS x 1 at 2 ohms

A high-output subwoofer amplifier engineered for both automotive and marine use. The JL Audio XDM300/1 blends design elements from JL Audio's M Series marine amps and the XD Series car amplifiers to deliver robust, reliable bass performance in demanding electrical environments. Built with marine-grade materials, the amp includes a selectable dual-mode power input filter to prevent noise whether it's installed in a boat or a car. JL Audio's proprietary NexD™ ultra-high-speed, highly efficient amplifier topology provides clean, powerful output without overtaxing your vehicle's electrical system. Performance and tone control are handled with care: the XDM300/1 supplies up to 300 watts RMS to a subwoofer and offers a low-pass filter with selectable slopes so you can tailor bass character and roll-off. "Differential-balanced" inputs reduce susceptibility to external noise and make it easy to hook the amp to a wide variety of head units, including many factory radios. Speaker-level inputs with two auto turn-on modes simplify integration into factory systems, and an optional wired remote lets you adjust subwoofer level from the driver's seat.
