What do you do? Set your speaker and mark your wholes and just drill some 1/4 inch wholes where marked, take your sub back out and feed the nuts up in the holes and hammer the nuts in the wood. And when they screw down into it it will lock into the wood?I guess it really doesn't matter then. I just liked the machine screws and T nuts, but they don't do much good if the holes don't line up. I guess I can't drill straight anymore ;0)
Heh,thumbtacks FTW
