Product Description

Alpine SBR-S8-4 Ported enclosure with one 8″ Type-R Subwoofer

Alpine SBR-S8-4 ported sub enclosure gives you the bass your system has been missing without taking up the valuable storage space you need. This enclosure is tuned by Alpine’s experts to give you impressive bass with minimal power requirements.

Powerful 8″ Type-R sub

Alpine SBR-S8-4 with an 8″ Type-R subwoofer, a speaker known for its serious bass performance. They created the ported, high-quality MDF enclosure as a perfect match for the sub, guaranteeing maximum punch while maintaining a very small profile.

Slim box makes placement easy

The Alpine SBR-S8-4 comes in at only 6-5/8″ deep so you can install it in a convertible’s trunk, behind the seat in your standard cab pickup, and in many other problem vehicles. Carpet protects the enclosure from nicks and scratches, while a metal grille protects your sub from flying objects and other hazards in your car.
