JL Audio VX1000/5i (D class) power amplifier (5-channel).

5-Channel Class D System Amplifier with Integrated DSP, 100 W x 4 @ 2 Ω + 600 W x 1 @ 2 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.
Employing our second generation NexD2™ amplifier technology, the VX1000/5i efficiently powers a complete audio system. 
It can drive four main speakers with 75 W x 4 @ 4 ohms while also powering a subwoofer with up to 600W @ 2 ohms. 
Bridging the main channels converts it into a very powerful, 3-channel system amplifier with up to 200W x 2 @ 4 ohms on the main channels and 600W @ 2 ohms on the subwoofer channel.
The NexD2™ full-range technology in the main channels of 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 subwoofer channel features an optimized low-frequency variant of the NexD2™ technology. 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.
