The biggest advance - in the smallest package. Introducing the KEY smart amplifier and audio processor in one, featuring AI-driven DSP. 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. In addition to an unbelievable sound quality, the KEY200.4 delivers 200 watts of pumpin' power to your factory speakers. The KEY200.4 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.
