The space-smart design, featuring 9" top and 12 1/4" bottom depths, fits snugly in tight spots without sacrificing bass response, giving American drivers powerful sound in a compact package.

Built Tough, Hits Hard

Engineered from 3/4" high-quality MDF, this enclosure delivers long-lasting strength while minimizing vibration for clean, powerful bass under heavy loads. Precision-sealed with Titebond silicone and glued for an airtight fit, it locks in every note for consistent, heart-pounding performance. Wrapped in rugged trunk-liner carpet, it resists scratches, spills, and daily wear, giving American car audio enthusiasts a durable, premium-looking enclosure that performs as hard as it looks.
