JL Audio XD400/4v2
4-Channel Class D Full-Range Amplifier
100 W x 4 @ 2 Ω / 75 W x 4 @ 4 Ω - 14.4V
This tiny amplifier packs a serious full-range punch, delivering a staggering 100 watts to each of its four channels into 2 ohms (14.4V, 1% THD). The breakthrough that makes this much power possible in such a small chassis is our NexD™ ultra-high-speed switching design, which allows for full bandwidth Class D operation with extremely low distortion and outstanding efficiency.
Use the XD400/4v2 in combination with our XD600/1 monoblock to build a 1000 W amplification system to power four satellites and a subwoofer... and fit the whole thing under a seat. Or, use the XD400/4v2 by itself to power two satellites, plus a subwoofer. With XD's, the possibilities are endless.
The XD400/4v2 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.
The XD400/4v2 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.
