To do what we can to protect our home community of Stillwater, we are temporarily closing the doors to the KICKER Visitors Center and Museum, until further notice.

Stillwater Designs and KICKER itself, including orders and shipping, will continue to run under normal business operations.

Thank you for your patronage and patience, and please plan to visit the KICKER Visitors Center when it opens again. If you want to visit a local KICKER dealer in your area, we recommend calling ahead to confirm store hours and availability.

KEY200.4 Smart 4-Ch. Amplifier (auto-EQ/processor)
The biggest advance - in the smallest package.
Introducing the KEY smart amplifier and audio processor in one, featuring AI-driven DSP.

Pasmag Reviews the Key Smart Amplifier

Designed specifically to greatly improve the sonics of a typical “deck and four” or OEM sort of system, the Kicker KEY amplifier uses powerful digital signal processing to bring concert realism to your car. Read the full review here.

ACOUSTIC CORRECTION = AUDIO PERFECTION

Don't just make your system louder - make it clearer. Make it better…

Press the selector, and the 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 a 24dB crossover re-defines 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.

Start with these FREE TEST TONES for easy setup!

POWERHOUSE

In addition to an unbelievable sound quality, the KEY200.4 delivers 200 watts of pumpin' power to your factory speakers. At KICKER, we know power and clarity always go hand-in-hand.

HIDDEN TREASURE

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.

START. DON'T STOP.

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.

KEEP THE BEAT

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. The amplifier quickly cools, which deactivates the compressor. Music returns to its full dynamic range without a moment’s interruption!
