Description
Get larger-than-life bass performance with Alpine's 12"" BassRev™ Powered Shallow Subwoofer Enclosure with built-in OPTIM™Sync technology.

Shallow, Sealed Design
Designed with flexibility in mind, this shallow, sealed enclosure tucks into places bulky boxes won’t—under seats, against trunk walls, or tight hatch areas—preserving your cargo room and install options. Paired with the integrated OPTIM™ Sync algorithm that intelligently enhances low-end performance, PWV-SB12 delivers the impact and authority of a full-size sub from a compact package that won’t steal your trunk.

OPTIM™Sync Technology
The PWV-SB12 uses Alpine’s proprietary bass algorithm OPTIM™Sync, built into the integrated DSP amplifier. It actively applies dynamic bass-boost and pre-EQ to the subwoofer, pushing harder where it counts while staying controlled. The result is larger-than-life low-end and a smoother tone, so this shallow 12"" enclosure hits with full-size sub authority.

Clean. Sturdy. Loud.
Built for daily use, the PWV-SB12's carpeted MDF cabinet and double-brace structure stay solid and rattle-free, even when you turn it up. An extended grille shields the woofer from kicks, pets, and sliding cargo, while the Alpine-embroidered top keeps the install looking premium. Shallow and compact it installs cleanly, feels rock-solid, and keeps performance front and center.
 
Factory-Friendly Integration
The Pwv-SB12 connects seamlessly to most factory or aftermarket systems. Easy, clearly marked controls make initial tuning fast, and the included wired remote puts bass level at your fingertips while driving. You keep the clean, stock look and everyday convenience, while your music gets the punch and depth your door speakers can't deliver.
