Another question im doing double layer baffle on the box would i wood glue them together then screw them THEN cut out the hole for the subs or how would i go about doing this?
when i glue to pieces together, i apply lots of glue, put a few screws in where i plan on cutting off, then drive my car on it and let it sit for an hour or so. Extreme clamping pressure.
Sometimes use another piece on top and bottom to distubute the weight evenly.
I would imagine its a little bit easier to the hole before you glue them. A jigsaw or router going through 3/4" instead of 1.5" is a pretty big difference.
