47KEY500.1

The KEY500.1 is a smart subwoofer amplifier and audio processor in one, featuring an AI-driven DSP (digital signal processing). Craft your sound with ease! The KEY500.1 comes with 24dB sub-sonic and low-pass crossovers, bass boost and gain controls. Measuring about eight inches long and less than two inches high, the KEY500.1 fits nearly anywhere. Mount it behind your glove box, under the seat, or in your trunk with ease.

The amplifier also features FIT+ (Fail-safe Integration Technology PLUS) – which provides nearly universal compatibility with stock or aftermarket radios. Another industry first, the KEY500.1 is uniquely suited to accept factory input signals as high as 40 volts (400 watts). The KEY amplifier will work with almost every car on the road today, whether you have a factory or aftermarket audio system.

Kicker Simplicity

This amp was easy to install in a small space, setup was easy using supplied directions. added this amp to boost the subwoofer on my Porsche BOSE system. I have used the Porsche subwoofer enclosure upgraded with a Audiofrog 8 inch driver and a 500 w Kicker Key amp. Big improvement over stock.

Amazing Tech

This amp’s auto de-eq feature works amazing and is so easy to set up. It ends up sending a clean flat signal the sub. It has more than enough power for daily use to feel music with great sound quality. I have this powering a JL audio 12w1 in a sealed box and it’s sounds so clean!
