Q Power QBOMB124T Quad 12 Inch Sealed Subwoofer Box with Spray-On Bedliner

Q Power builds enclosures that hit hard and last long, engineered for bass lovers who want performance without compromise. The Q Power Quad 12-Inch Sealed Subwoofer Box takes that legacy further with a 4-hole design built for clarity, control, and durability you can depend on.

Featuring four sealed chambers, this box pairs two front-firing and two top-firing subwoofer mounts to create a powerful yet balanced low-end presence. Each chamber provides 1.0 cubic foot of air space, carefully tuned for sealed setups that deliver tight, punchy bass with fast response and minimal distortion. The result is clean, controlled sound that enhances every note, whether you’re cruising or competing.

Constructed from durable MDF with internal bracing, the subwoofer box keeps your subs stable under heavy load, reducing flex and unwanted resonance. Its spray-on bedliner coating gives the enclosure a rugged, moisture-resistant finish that stands up to impact, scratches, and time. The textured surface adds grip and a professional appearance that looks as tough as it sounds.

With high-quality spring-loaded terminals, wiring is quick, secure, and reliable, designed to keep connections solid no matter how hard your system hits. Whether you’re building a showpiece or a daily driver with authority, the Q Power Quad 12-Inch Sealed Subwoofer Box delivers consistent, hard-hitting performance and lasting build quality.
