Designed to simplify great audio, the JL Audio VX400/4i combines a high-efficiency 4-channel Class D amplifier with a fully integrated digital signal processor. Using second-generation NexD2™ switching technology, it delivers up to 75 watts per channel into 4 ohms or 100 watts per channel into 2 ohms at 14.4V. The amplifier can also be bridged to produce up to 200 W x 2 into 4 ohms, providing excellent flexibility for multi-speaker system designs. The DSP-controlled NexD2™ architecture features a reduced loop area design with DirectFET™ outputs, ensuring outstanding sound quality, very low noise and exceptional efficiency. Instead of traditional controls, all amplifier and DSP adjustments are handled digitally via JL Audio TüN® software using a compatible PC, tablet or smartphone. Its ultra-compact chassis places all connections on one side using mating plugs, making installation straightforward in tight vehicle locations.
