Overview

The Skar Audio SK1X8V is part of the SK Series, designed to bring competition-grade quality into a universal-fit, pre-fabricated enclosure.

The enclosure arrives wrapped in premium black carpet and features the Skar Audio logo on the lower left side, signaling a premium build that looks at home in any install.
