4-Channel Amplifier with Automatic DSP and Built-In EQ/Processor, 50-Watts RMS @ 4-Ohms x 4ch Kicker KEY series amplifiers use a powerful internal computer to deliver dramatic improvements in realism and soundstage. A massive 40-band equalizer improves tonality, and a 24dB crossover re-defines the capabilities of each speaker. The KEY200.4 delivers 200 watts RMS of power to your speakers. Measuring less than eight inches long and only two inches high, the KEY200.4 fits nearly anywhere. Mount it behind your radio, under the seat, or in your trunk with ease.  If the temperature reaches the threshold, the Kicker KEY200.4's dynamic power-management algorithms kick into gear! Instead of hearing the amplifier's volume “pumping” or blowing a fuse – KEY technology engages a nearly inaudible limiter/compressor, applied only to the peaks of the music for as little as milliseconds at a time. The amplifier quickly cools, which deactivates the compressor. Music returns to its full dynamic range without a moment’s interruption!

4-Channel Class-D Full-Range Amplifier with Integrated DSP, 100-Watt x 4 @2-Ohm / 75-Watt x 4 @ 4-Ohm Designed to simplify great audio, every VXi amplifier combines JL's advanced NexD2™ switching amplifier technology with an integrated, full-featured digital signal processor. With JL's second-generation NexD2™ technology, the VX400/4i full-range 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 utilizing 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. Amplifier includes: Power Connector (for 4 AWG wire), Analog Input/Pre-Out Harness, Speaker Output Harness, 6 ft A/B USB Cable TüN™ Software Applications Intuitive setup and tuning, all at your fingertips. Automatically recognizes connected amplifier and displays appropriate interface. TüN™ is available for download for free in a variety of applications, for computers and most handheld devices.
