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 NexDTM ultra-high-speed switching design, which allows for full bandwidth Class D operation with extremely low distortion and outstanding efficiency.

Use the XD400/4 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 XD400/4 by itself to power two satellites, plus a subwoofer. With XD's, the possibilities are endless.

The XD400/4 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 HD-RLC remote level control (sold separately), the amplifier's Ch. 1 & 2 level or overall 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.

Amazingly small in size, but huge in audio performance, the JL Audio XD amplifiers are the perfect solution for space-conscious installations or for anyone seeking affordable excellence in a mobile amplifier. As with their more expensive HD siblings, XD's also deploy our Advanced Thermal Rollback System to completely eliminate annoying thermal shut-down events. Beneath every XD's removable control cover, you will find studio-grade signal processing with fully variable crossover filters. Also included are our noise-killing, highly flexible differential-balanced inputs with remote level control capabilities via the HD-RLC remote level control (optional).
