Monoblock Class D Subwoofer Amplifier with Integrated DSP, 600 W x 1 @ 2 Ω / 400 W x 1 @ 4 Ω - 14.4V

Designed to simplify great audio, every VXi amplifier combines our advanced NexD2™ switching amplifier technology with an integrated, full-featured digital signal processor.

The VX600/1i monoblock subwoofer amplifier outputs up to 400 watts into 4 ohms, or a staggering 600 watts into 2 ohms. A specialized, low-frequency version of our NexD2™ amplifier technology delivers rock-solid bass performance and fidelity, with outstanding efficiency. Compact dimensions with all connections placed on one side, via mating plugs, 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, Subwoofer Output Connector, 6 ft A/B USB Cable
