Sub Box Anchor

Subwoofer box anchor. Using a zip-tie around the headrest post of my 3rd row seat around the threaded screw of this anchor keeps the sub box from sliding. The wing nut screw gives you a way to detach when you need to remove the box/put your seat down without cutting the zip-tie. You could also use a zip-tie with a screw eyelet screwed into the back of the seat support if you wanted to use it in a car trunk (1" screw or shorter for passengers sake). ABS filament recommended. Superglue recommended
