Kicker’s Key Smart Amplifier

Bump Up the Tunes


Kicker Key smart amplifier


Kicker’s Key smart amplifier uses a powerful internal computer to provide dramatic improvements in realism and soundstage. Its 40-band equalizer improves tonality as a 24-dB crossover redefines each speaker’s capabilities. The KEY 180.4 also puts 180 watts of power to your car’s factory speakers and is fully compatible with cars that have stop-start systems. The KEY 180.4’s compact size allows it to fit anywhere—under seats, behind the radio, or in the trunk. It’s also compatible with nearly every stock and aftermarket radio with its FIT2 technology.

ABOUT Kicker®

KICKER began in 1973 as a two-man operation, hand-building professional-speaker systems in a narrow one-car garage. With very few resources and an intense love for music, company founder and current president Steve Irby invented the mobile-stereo enclosure market from his Stillwater, Oklahoma community, when he developed the Original KICKER. It was the first full frequency-range speaker box designed specifically for cars and trucks. From that historic moment, delivering concert-like audio quality across a wide volume range with renowned bass and accurate sound has always been the KICKER way.
