Looking to add serious low-end to your truck without giving up valuable space? The Alpine SWT-10S4 10-inch subwoofer is built specifically for tight truck installations, delivering the kind of deep, hard-hitting bass you’d expect from a much larger sub. With 350W RMS and 1000W peak power handling, this single 4-ohm subwoofer is ready to bring your music to life with plenty of punch and authority.
The SWT-10S4 is only 4-3/16 inches deep, making it an excellent choice for behind-seat, under-seat, and other space-conscious installations. But don’t let the shallow design fool you—the FEA-optimized motor structure and Alpine’s H.A.M.R. suspension help deliver an impressive 11mm of real-world X-max for big output and controlled bass. The poly-mica/pulp-Kevlar cone, high-temperature 4-layer voice coil, and airflow-focused motor design are built to handle the demands of serious bass.
Whether you prefer a sealed or ported enclosure, the Alpine SWT-10S4 gives you the flexibility to build a bass system around your available space and listening style. Its 30Hz–200Hz frequency response and 350W RMS rating make it a strong upgrade for truck owners who want deeper, louder, and more impactful bass without installing a massive enclosure. If you want a compact Alpine subwoofer that can deliver real bass without sacrificing cabin space, the SWT-10S4 is a serious contender.

Hits hard, powerful bass, and its built well. doesn't take up much space, and the manual says that it can go down to 30Hz? I think it can go even lower than that.
can't really get any better for the price with the sub. hard, loud, but tight bass that you can really feel. already recommended to my brother and he's getting one next week. perfect for trucksGr
Its shallow but wow the bass really hits that hard. Such power for its size. and really built well. It really feels like a premium sub
