Bbox Single Sealed 12 Inch Subwoofer Enclosure - Accu-Tuned Sealed Subwoofer Boxes - Subwoofer Box Improves Audio Quality, Sound & Bass - Fits 1999-2007 Chevrolet/GMC Silverado/Sierra Extended Cab

SINGLE 12 INCH SEALED SUBWOOFER ENCLOSURE: The Bbox 12 inch single sealed Accu-Tuned subwoofer box enclosure is designed for optimum bass response and low frequency reproduction which is ideal for lower profile sound quality subwoofers. Get the most out of your vehicle's subwoofer with car stuff designed for power and quality.
SPECIAL FORMULA: We use Aliphatic wood glue on our 12" subwoofer enclosures to ensure an airtight seal between all MDF parts. Each 12 inch subwoofer box also gets a second application of glue around all internal joints after the final assembly.
HIGH GRADE MDF: Our subwoofer box enclosures are built with a durable MDF that is 3/4" thick for solid frequency response and accurate music reproduction and we use a CNC Miter to ensure an airtight fit for your powered subwoofer. Our Dado design and construction offers a precision fit for our car subwoofer boxes & enclosures, which ensures a rattle and noise free environment.
AIRTIGHT RECESSED SIDE PANELS: We use quality materials like our special aliphatic resin wood glue and brad nails from a pneumatic nail gun to create a tight hold on the MDF parts during the glue drying process to ensure that our subwoofer boxes have an airtight no-leak, no-rattle air chamber improving the overall sound quality of your sound system
