I owned a car audio shop for about 10 years, but I closed down about 6 years ago. All of the sub boxes that I built I used wood screws and liquid nails or wood glue. I have seen a few boxes on here that seem to be held together with just wood glue and no screws. Will a sub box hold up to the pressure if you dont use wood screws to anchor it down? Or is everyone using wood screws and I just cant tell from the pics.
