The KICKER KEY500.1 is a mono subwoofer amplifier and audio processor in one. It uses AI-driven digital signal processing (DSP). Its Auto EQ analyzes the incoming audio using KICKER's supplied test tones. It then corrects peaks in the signal and restores low bass that is often missing.
Controls include 24dB sub-sonic and low-pass crossovers, bass boost and gain. The amplifier is compatible with the CXARC remote control, which adjusts bass with a knob.
The amp measures about eight inches long and less than two inches high, so it can be mounted behind a glove box, under a seat or in a trunk. FIT 2+ (Fail-safe Integration Technology 2 PLUS) allows use with stock or aftermarket radios. It accepts factory input signals as high as 40 volts (400 watts).
