The Biggest Advance - In The Smallest Package
The Kicker KEY 200.4 represents a revolutionary breakthrough in automotive audio technology, combining a smart amplifier and audio processor in one compact unit featuring AI-driven DSP.
Automatic Sound Optimization
Press the selector, and the included microphone goes to work. The KEY uses a powerful internal computer to deliver dramatic improvements in realism and soundstage. A massive 40-band equalizer improves tonality, and 24dB crossovers re-define the capabilities of each speaker. The concert quality of your factory stereo is revealed! What would take hours for a professional to achieve happens in a matter of minutes - all automatically, all with the press of a single button.
Powerhouse Performance
In addition to unbelievable sound quality, the KEY200.4 delivers 200 watts of power (50W x 4 channels @ 4 ohms) to your factory speakers. At KICKER, we know power and clarity always go hand-in-hand.
Compact & Versatile Design
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.
Advanced Vehicle Compatibility
The KEY200.4 is one of the first amps fully compatible with newer vehicles using start-stop systems. The amplifier also features FIT2™ (Fail-Safe Integration Technology), providing compatibility with nearly every stock and aftermarket radio on the road today.

Smart Temperature Management
If the temperature reaches the threshold, the 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.
