Kicker Smart Monoblock Subwoofer Amplifier Bass Boost 500W 1/2/4Ohm +Install Kit

The KEY500.1 is a smart subwoofer amplifier and audio processor in one, featuring an AI-driven DSP. Using KICKER’s supplied test tones, 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. The KEY500.1 comes with 24dB sub-sonic and low-pass crossovers, bass boost and gain controls. The amplifier also features FIT 2+ (Fail-safe Integration Technology 2 PLUS) – which provides nearly universal compatibility with stock or aftermarket radios. KEY amplifiers are fully compatible with nearly every stock and aftermarket radio on the road today, including newer vehicles equipped with start-stop systems. This small, powerful amplifier includes built-in DSP (digital signal processing) that gives you built-in gain match, KickEQ Bass Boost, and a simple automatic calibration to give you dramatically improved bass response in minutes
