It pairs two SDR-8 D4 subwoofers with a purpose-built enclosure to deliver powerful low-end response in a compact footprint. The design emphasizes efficiency, ease of installation, and a clean, integrated appearance in a variety of vehicles.

With a thoughtful combination of a kerf middle port and a split chamber woofer configuration, the enclosure aims to balance deep bass with midrange clarity. The enclosure is finished in premium black carpeting and features the Skar Audio logo on the top surface for a subtle, refined look that fits most dashboards and trunks.
