Custom Dual 12in Chevy C/K Extended Cab 88-98 Sub Enclosure - Clean

Our review looks at the American Sound Connection Custom Dual 12in Chevy C/K Extended Cab 88-98 Truck Sub Enclosure and finds it best suited for truck owners who want a tidy, factory-like subwoofer solution. The single biggest reason to consider this enclosure is its precise custom fit for the rear seat area of 1988-1998 Chevrolet C/K extended cabs, which keeps subwoofers out of the way while delivering serious low-frequency impact. It is not a universal box; this review focuses on fit, construction quality, and how the enclosure affects sound when paired with compatible 12in subwoofers.

Key Features

• Premium craftsmanship: Rigid, road-ready construction resists wear and maintains a neat appearance under the rear seat for long-term use.
• Custom fit: Engineered specifically for 1988-1998 Chevy C/K extended cabs so it integrates cleanly with the vehicle interior and conserves cabin space.
• Dual 12in capacity: Designed to house two 12in subwoofers to provide deep, powerful bass without sacrificing a factory look.
• Optimized sound control: The enclosure shape reduces unwanted vibrations and resonances so subwoofers can reproduce clearer bass.
• Compact depth: A mounting depth of 5in makes it compatible with the majority of popular 12in subwoofers for easier driver selection.
• Measured air space: Approximately 0.95 cubic ft total internal volume tuned to increase output for many sealed 12in designs.

Who It's For

Truck owners with a 1988-1998 Chevrolet C/K extended cab who want to add substantial bass while preserving under-seat storage and a factory-like interior will benefit most from this enclosure. Installers and DIYers who value fitment and appearance over a generic, bulky trunk-mounted box will appreciate the clean integration and straightforward mounting.

Those who should look elsewhere include drivers with other truck models or owners who need ported, high-volume enclosures for extreme SPL competition; this is a sealed, custom-fit solution focused on balance between space and impactful low-end rather than maximum output for contest builds.
