BassMaxx P210PG5CF Ported Dual 10" Under-Seat Subwoofer Enclosure | 2019+ Silverado & Sierra Crew Cab

Purpose-Built Bass for Your New-Body Silverado or Sierra — BassMaxx P210PG5CF Dual 10" Ported Under-Seat Enclosure

If you own a 2019-and-up Chevrolet Silverado or GMC Sierra Crew Cab and want serious bass without sacrificing your back seat or bed space, the BassMaxx P210PG5CF is engineered exactly for that purpose. This vehicle-specific, front-firing ported enclosure installs clean under the rear seat, holds two 10" subwoofers in a tuned 2.9 cubic foot ported chamber, and finishes with a rugged MDF and bedliner construction that looks like it belongs there. No custom fabrication, no compromises — just bolt-in bass that fills your cab with the low-end your factory system never had.

Key Features

• Vehicle-Specific Fit: Designed exclusively for 2019-and-up Chevrolet Silverado and GMC Sierra Crew Cab trucks — installs under the rear seat without modification.
• Dual 10" Front-Firing Ported Design: Forward-firing port and woofer orientation delivers maximum bass output into the cab for a powerful, enveloping low-end experience.
• 2.9 Cubic Foot Internal Volume: Generous ported enclosure volume tuned for deep, authoritative bass from a wide range of 10" subwoofers.
• MDF Construction with Bedliner Finish: Heavy-duty MDF shell with a durable bedliner coating that resists scuffs, moisture, and the rigors of daily truck use.
• Speaker Terminal Cup Included: Clean, professional-grade input terminal makes wiring your subwoofers straightforward and secure.
• 9.125" Cutout Diameter: Compatible with most standard 10" subwoofer baskets — fits a wide range of brands and models.

Why the BassMaxx P210PG5CF?

Most truck owners end up with a generic enclosure that doesn't fit cleanly, takes up cargo space, or rattles against the seat. The P210PG5CF eliminates all of that — it's built to the exact dimensions of the new-body Silverado and Sierra's under-seat cavity, so it sits flush, installs cleanly, and delivers front-firing ported bass that hits harder than anything that shape has a right to. If you're building a system in a '19-and-up Silverado or Sierra, this is the enclosure to start with.
