Deliver deep, thunderous bass in your Chevy Silverado with this 8" dual-ported sub box, engineered for precise low-end performance. With a 7 1/8" cutout diameter, 2.50 ft³ air volume, and a 32 Hz tuned slot port, it produces tight, resonant bass that fills your cabin. Weighing 58 lbs with a 7 1/4" mounting depth and a 1 1/4" front baffle, it’s built for a secure, forward-firing under-seat installation.
With a front height of 9 3/4 inches and a rear height of 6 1/2 inches, this sub box fits neatly under your Silverado’s rear seat for a clean, low-profile installation. Its 53" length maximizes internal volume for deeper, more powerful bass. A 17" depth ensures stability and durability, delivering a secure, long-lasting setup for premium forward-firing sound.
Crafted from 5/8" high-quality MDF wood, this sub box is built to withstand powerful bass while providing long-lasting strength. It’s carpeted with a rugged trunk liner finish and sealed with high-quality Titebond silicone and wood glue for an airtight, vibration-free enclosure. Equipped with 2 spring-loaded terminals, it ensures a secure, reliable connection for easy installation and professional-grade audio performance.
