Designed to simplify great audio, every VXi amplifier combines JL Audio's advanced NexD2™ switching amplifier technology with an integrated, full-featured digital signal processor.
With second-generation NexD2™ technology, the JL Audio VX400/4i - 4 Channel Class D 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 utilising 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.
The amplifier includes Power Connector (for 4 AWG wire), Analog Input/Pre-Out Harness, Speaker Output Harness, 6 ft A/B USB Cable.
