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.


Measuring less than eight inches long and only two inches high, the KEY180.4 fits nearly anywhere. Mount it behind your radio, under the seat, or in your trunk with ease.


The KEY180.4 is one of the first amps fully compatible with newer vehicles using start-stop systems. The amplifier also features FIT2™ (Fail-Safe Integration Technology), providing compatibility with nearly every stock and aftermarket radio on the road today.
