Hear the Difference!

Experience fidelity for all and crystal-clear audio in your boat or car with the xdm amplifier's exclusive dual-mode input filter and differential-balanced inputs for outstanding noise rejection, while the NEXD™ equipped advanced switching technology delivers reliable high-power output from a compact chassis by reducing current draw and heat, all benefiting from studio-grade signal processing featuring audiophile-grade, fully variable filters and calibrated potentiometers beneath a sealed security cover.

Uninterrupted Power and Built to Last!

With ADVANCED ROLLBACK PROTECTION, our innovative circuit design ensures the amplifier will never shut down due to thermal overload, keeping your music playing even under the most demanding conditions, all while offering flexible AUTO TURN-ON CAPABILITIES (via auto signal sensing, auto DC-offset sensing, or conventional +12 volt turn-on lead), and a BUILT TOUGH all-aluminum, powder-coated housing that inhibits corrosion and features a sealed security cover to protect controls from the elements.
