What kind of subwoofer does this fit?
This enclosure is precision-built for a single shallow-mount 12" round subwoofer. The cutout diameter is exactly 11.00" and it is engineered specifically for low-profile, slim drivers requiring a maximum mounting depth of 4.75".

Will it fit in my vehicle?
Yes, it features an ultra-compact, space-saving wedge downfire footprint designed to slip into extremely tight spaces. Its shallow depth (7.25" bottom depth tapering to 6.25" top depth) makes it an excellent solution for truck cabs, behind or under seats, or inside compact cargo spaces where every inch matters. The exact external dimensions are 16.25" W x 13.50" H x 7.25" D1 (Bottom) x 6.25" D2 (Top).

How is the performance and wiring?
This enclosure features a specialized downfiring configuration that naturally loads the subwoofer against your vehicle's floor pan, increasing structural acoustic coupling to deliver deep, rich, and highly localized bass reinforcement. The downfire alignment also keeps the fragile subwoofer cone completely concealed and protected from shifting cargo. The airtight sealed chamber provides incredibly tight, punchy transients with great power handling. It comes equipped with a high-grade speaker terminal cup featuring gold-plated binding posts for secure, reliable wiring connections.

Works good
Size: 16AWG -20FT 2Pcs
I used it to set up some extra pods on the back of my truck, and having that full 20 feet of length made it so much easier to route everything cleanly without having to splice in extra wire. The 16-gauge copper feels heavy-duty and is protected by a thick PVC jacket that seems like it’ll hold up well against heat and the elements. It’s a simple plug-and-play setup that saved me a ton of time, and the connections snap together with a really solid, secure click. If you’re doing a custom lighting build on a larger vehicle or a boat, this kit is a total lifesaver for keeping your wiring looking professional and staying reliable.
