KICKER KEY500.1 - Smart Mono Amplifier (bass revealer/processor) - 500 RMS

The KICKER KEY500.1 is a compact mono subwoofer amplifier with integrated AI-driven DSP, designed to deliver powerful, accurate bass while automatically correcting factory audio limitations. By intelligently analysing the incoming signal, the KEY500.1 restores missing low frequencies and smooths uneven bass response — all without the need for complex tuning.

Perfect for factory or aftermarket systems, the KEY500.1 provides clean, controlled bass output in a wide range of modern vehicles.

Automatic Bass EQ & Signal Correction

Using KICKER’s supplied test tones, the KEY500.1 automatically analyses the audio signal being fed into the amplifier. Once analysed, the built-in DSP corrects peaks and restores low-frequency information commonly lost in factory systems.

The result is a clean, even bass response achieved in moments — no laptops, tuning software, or manual EQ required.
