2-Channel Class D Full-Range Car/Marine Amplifier, 100 W x 2 @ 2 ? / 75 W x 2 @ 4 ? - 14.4V The tiny XDM200/2 packs a serious full-range punch, delivering a staggering 100 watts per channel into 2 ohms (14.4V, 1% THD). The technology that makes this much power possible in such a compact chassis is our advanced NexD™ high-speed switching design, which permits full bandwidth Class D operation with extremely low distortion and remarkable efficiency. Suitable for car or boat installations, the XDM200/2 is built with marine-grade materials and features an exclusive, dual-mode input filter for noise-free performance in boats or cars. Automatic turn-on capability (via signal sensing or DC-offset sensing) is also onboard for easy factory system upgrades. The XDM200/2 includes a 12 dB / octave filter which can be configured as a low-pass or high-pass filter and offers continuously variable cutoff frequency selection from 50-500 Hz. With the addition of an optional HD-RLC or MHD-RLC (water-resistant) remote level controller (each sold separately), the amplifier's level can be adjusted directly from the driver's seat or cockpit. Finished in a sleek, black powder-coat, all controls are protected beneath a gasketed, removable top cover for easy access.
