Kicker 53KEY2004 KEY200.4 4-Channel Smart Amplifier with Auto-EQ DSP

Upgrade a factory or aftermarket car audio system with clearer sound, better staging, and compact four-channel power. The Kicker KEY200.4 combines a 200-watt amplifier with automatic digital signal processing that tunes the system in minutes using the included setup microphone.

Smart automatic tuning

Press the selector and KEY technology analyzes the vehicle, then applies a 40-band equalizer, automatic time alignment, speaker-size detection, level adjustment, and 24 dB crossovers. It delivers the kind of tuning that would otherwise require extensive manual setup.

Compact power for factory systems

The KEY200.4 supplies 50 watts RMS to each of four channels at 4 ohms. Its compact chassis fits behind many radios, beneath a seat, or in the trunk. FIT2 integration technology accepts high-level factory-radio signals, while start-stop compatibility helps it work reliably in newer vehicles.
