KEY200.4 Smart 4-Ch. Amplifier (auto-EQ/processor).

Features automatic signal processing that optimises the sound specifically for your vehicle's interior. 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.

Once the amplifier has been installed and wired up, you connect the included calibration microphone to the amp and put it on the drivers headrest, play the test tone (downloaded from Kicker), press the activation button, and let the KEY Auto Setup software automatically configure the crossovers, 40-band EQ, and time-align the sound for the front seat driver. You can then use the button on the microphone to toggle between the before- and after-processing sound, impressing your friends and family.

Powerhouse
In addition to an unbelievable sound quality, the KEY200.4 delivers 200 watts of pumpin' power to your 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 boot 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!
