JL Audio VX400/4i : 4ch x 75W/100W Digital DSP Amplifier @ 4Ω/2Ω
4-Channel Class-D Full-Range Amplifier with Integrated DSP, 100-Watt x 4 @2-Ohm / 75-Watt x 4 @ 4-Ohm.
Designed to simplify great audio, every VXi amplifier combines JL's advanced NexD2™ switching amplifier technology with an integrated, full-featured digital signal processor.
With JL's second-generation NexD2™ technology, the VX400/4i full-range amplifier outputs up to 75 watts per channel into 4 ohms, or 100 watts into 2 ohms. It can also be bridged into 4 ohms, producing up to 200 W x 2.
The NexD2™ full-range technology in this amplifier is DSP-controlled and features a reduced loop area design utilizing DirectFET™ outputs for outstanding fidelity, very low noise and exceptional efficiency. The amplifier chassis is ultra-compact, with all connections on one side, to greatly simplify installation into tight spaces.
Instead of traditional control knobs and switches, all amplifier adjustments and DSP functionality are configured via a compatible external device (PC, Tablet or Smartphone), with the appropriate JL Audio TüN™ Software application installed.
Amplifier includes: Power Connector (for 4 AWG wire), Analog Input/Pre-Out Harness, Speaker Output Harness, 6 ft A/B USB Cable
TüN™ Software Applications
Intuitive setup and tuning, all at your fingertips. Automatically recognizes connected amplifier and displays appropriate interface. TüN™ is available for download for free in a variety of applications, for computers and most handheld devices.

I have a 'pickup in store only' item that I need to add to my cart. Will you ship it?
