XD500/3v2 3 Channel Car Amplifier

3-Channel Class D System Amplifier, 75 W x 2 @ 4 Ω + 300 W x 1 @ 2 Ω - 14.4V

This compact amplifier is ideal for a simple audiophile-grade, subwoofer / satellite system. With the XD500/3v2, you can drive a pair of quality component speaker systems with plenty of clean power, while also delivering a stout 300 W to your subwoofer system. The breakthrough that makes this much power possible in such a small chassis is our NexD™ switching design.

The XD500/3v2 includes a 12 dB / octave high-pass filter for its main channels, plus a variable slope low-pass filter for its subwoofer channel. Both filters offer continuously variable cutoff frequency selection from 50-500 Hz.

The XD500/3v2 also features the v2 Spec feature set, which consists of automatic turn-on capability (via signal sensing or DC-offset sensing), and a dual-range differential-balanced input section able to handle a wide range of input voltage levels. With the addition of an HD-RLC remote level control (sold separately), the amplifier's level can be directly controlled from the driver's seat.

This amplifier features a black powder-coat finish and a gasketed, brushed aluminum cover for the controls.
