The Key Smart Amplifier


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!

f the temperature reaches the threshold, the KEY180.4’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! Another novelty of kicker sound system.

This small amplifier provides a great sound that apparently due to the size one is left with doubts if it will be layers of providing high quality in the voice, well for surprise let them tell you that if you really manage to expand the sound with a high quality of voice and clarity in the sound, very good I recommend it to greatly improve the sound with Factory Head Units.
