This potent monoblock amplifier employs our high-speed NexD™ switching design to achieve unprecedented efficiency and amazing power output in a very compact chassis. Don't let the small size fool you, though... this amplifier is capable of serious subwoofer power, delivering a full 600 W of continuous power into a 2 ohm load (14.4V, 1% THD). Targeted specifically for subwoofer applications, the XD600/1 includes a variable slope low-pass filter with continuously variable cutoff frequency selection from 50-500 Hz. 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.
