Kicker 45KEY1804 180 watt 4 Channel Key Smart Amplifier

The biggest advance - in the smallest package.
Introducing the KEY smart amplifier and audio processor in one, featuring A.I.-driven DSP.

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.
