if you're only running subs with a couple hundred watts, just use the screws into the particle board with the mentioned pilot hole. If you feel you need more security and want to run with the tee-nut option, I would suggest using a glue of some sort to hold the tee-nuts in place to reduce the chance of pushing them out while threading your screw in from the front of the enclosure. <--I think that made sence. I may or may not have said a few bad words because of this.
