Our take on the CT2X12 Dual 12” Kerf Ported Universal Car Subwoofer Box

The CT Sounds CT2X12 is an empty dual 12-inch ported subwoofer enclosure with a kerf-style port, built for deep, accurate bass. It uses dado and miter joinery and recessed side panels for an airtight, vibration-resistant box, and comes pre-wired with 8-gauge terminals and 12-gauge internal speaker wire. It suits DIY bassheads who want custom-style performance without building a box. Compared with generic prefab boxes, its kerf port and sturdy construction stand out, though it needs two 12-inch subwoofers and an amp to complete the system.
