4-Channel Class D Full-Range Car/Marine Amplifier, 100 W x 4 @ 2 / 75 W x 4 @ 4 - 14.4V

The ultra-compact XDM400/4 packs a serious full-range punch,generating awhopping 100 watts to each of its four channels into 2 ohms (14.4V, 1% THD).Thetechnology that makes this much power possible in such acompact chassis is our advanced NexD high-speed switching design, whichpermits full bandwidth Class D operation with extremely low distortion andremarkable efficiency.

Suitablefor car or boat installations, the XDM400/4 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.

Combinethe XDM400/4 with our XDM600/1 monoblock to build a stunning 1000 W amplification system to power four satellites and a subwoofer... and fit the whole thing under a seat or deck. Or, use the XDM400/4 by itself to power two satellites, plus a subwoofer.

The XDM400/4 includes a 12 dB / octave filter for each channel bank, 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),you have the ability toadjust the level of all amplifier channels or just the rearchannels directly from the driver's seat or cockpit.

Finished in a sleek, black powder-coat, all controls are protected beneath agasketed, removabletop cover for easy access.
