About: Kicker 47KEY5001 500W RMS Compact Monoblock Amplifier with Automatic Tuning DSP

The KEY500.1 is a smart subwoofer amplifier and audio processor in one, featuring an AI-driven DSP (digital signal processing).

Auto EQ

Using KICKER’s supplied test tones (below), the KEY automatically analyzes the audio being fed into the amplifier. Once this signal has been analyzed, the amp will automatically fix peaks in the signal coming in and restore the low bass that is typically missing. In a matter of moments, you get a clean, even bass response from your amp!

All the Control 

Craft your sound with ease! The KEY500.1 comes with 24dB sub-sonic and low-pass crossovers, bass boost and gain controls.

Hidden Treasure

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.

Start. Don't Stop

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.
