Features
The Kicker KEY500.1 is a powerful yet tiny Class D mono subwoofer amplifier that fits almost anywhere in any vehicle. The centerpiece is the KEY Auto Setup, which uses a sine sweep and test tone to automatically analyze your system's response, applying equalization and bass boost for fantastic bass performance. It features preamp and speaker-level inputs with DC offset sensing turn-on. The Radio-Detect circuit prevents a "No Speakers Detected" message on your receiver. Advanced features include a variable low-pass filter (40-160 Hz, 24 dB/octave) and a variable subsonic filter (10-40 Hz, 24 dB/octave).
