The Infinity Kappa 1000W is a passive car audio subwoofer engineered to reproduce low-frequency bass. It is built as a single loudspeaker that requires an external amplifier and enclosure for installation.

Suitable for sealed or ported enclosures, the Kappa installs in standard aftermarket subwoofer boxes and connects to an amplifier via speaker leads or an amp input. Fitment depends on enclosure size and vehicle space.
