Designed to simplify great audio, the JL Audio VX600/1i combines a high-efficiency monoblock Class D subwoofer amplifier with a fully integrated digital signal processor. Using JL Audio’s advanced NexD2™ switching technology, it delivers up to 400 watts into 4 ohms or a powerful 600 watts into 2 ohms at 14.4V, producing tight, controlled bass with outstanding efficiency and low distortion. A dedicated low-frequency NexD2™ design ensures consistent, high-fidelity subwoofer performance even in demanding systems.

Instead of traditional control knobs, all amplifier adjustments and DSP functions are managed digitally via the JL Audio TüN® software, using a compatible PC, tablet or smartphone. This allows precise tuning of crossover settings, signal routing and system optimisation. Compact dimensions and a single-side connection layout using mating plugs make the VX600/1i easy to install in confined vehicle locations. Supplied accessories include power, input and output harnesses, plus a USB cable for fast configuration and setup.
