The KEY500.1 is a smart subwoofer amplifier and audio processor in one, featuring an AI-driven DSP. It automatically analyses incoming audio and fixes peaks while restoring low bass for a clean, even response. Compact dimensions allow it to hide behind a glovebox, under a seat, or in the boot. FIT 2+ technology ensures compatibility with stock and aftermarket radios, and it stays powered through Start/Stop systems. The variable low-pass and high-pass crossovers, bass boost, and gain controls let you craft the perfect sound.
