About this item

Written by Crutchfield's Bob Bihlmayer

Install Bay's port tube kits are made to simplify building your own ported subwoofer enclosure. The kit includes flared end caps that project the sound from your sub with minimal port noise, while their rolled edges give your install a clean custom look. The tube can be trimmed to the proper length for your enclosure.

All components are made of tough ABS plastic to stand up to the high temperatures of your vehicle's trunk or interior. You'll be able to maximize your sub's low-end impact and minimize the effort of creating your own custom-fit box.
