Save a buck, get bass for your truck Alpine designed their SBT-S10V ported sub enclosure to fit in the limited space in regular cab trucks and other space-challenged vehicles, while still giving you the bass you need. Alpine's experts have carefully tuned the enclosure to give you impressive performance with minimal power requirements. Powerful 10" Type-T sub Alpine loads the SBT-S10-V with the 10" SWT-10S2 2-ohm subwoofer, which was born to sound great in truck settings. Its high power handling and extended cone excursion deliver big, powerful bass, while its 2-ohm impedance ensures maximum output from most mono amplifiers. Compact enclosure Alpine's ported, high-quality MDF enclosure delivers maximum punch from its high-performance sub, and its compact size guarantees it'll fit behind most seats. Carpet protects the enclosure from nicks and scratches, while a metal grille protects the speaker from damage. You can see the embroidered logos at front and bottom of the enclosure whether the enclosure is mounted horizontally or vertically. It's a bass solution tailor-made for your truck.
