Product Description

The JL Audio XD400/4v2 is a perfect amplifier for powering 4 speakers. The XD400/4v2 puts out 75 watts of RMS power at 4 ohms and 100 watts at 2 ohms making it a perfect match for most quality car speakers. This amp uses JL's NexD switching technology to deliver clean power with incredible efficiency and low distortion. What makes the XDv2 amps superior to the RD and the JD is the advanced rollback thermal technology. The XD amps offer superior thermal management that will never shut down or over heat. The improved thermal management means less heat which means less distortion, and cleaner, better power. The XD amps just sound better than RD and JD.

The XD400/4v2 comes in a stylish black chassis with a silver control portective cover. This amp has 12dB/octave crossovers and high, low, and all pas filters. You have the option of running both high or low level inputs, the amp features automatic turn-on capability and has a selectable 2 or 4 channel input switch for the maximum installation flexibility. The XD400/4v2 has a 2-channel pre-amp output that allows you to easily add an additional amplifier to power more speaker or a subwoofer and you can select which channels you want to output.

Althought the XD400/4v2 does not have the LED clipping indicators that the JD and RD have, the output just sounds better. The JL Audio XD amps are the best sounding JL Audio amplifiers before you get into the MHD, Slash, and VXI which feature constant power circuits and built-in DSPs. The XD amps just sound better and they are as reliable as they get.
