Sub Box Screws Not Grabbing.
I recently purchased a 10'' truck sub enclosure off Rob at Forbidden Audio at this site (Highly Recommended BTW).
After I finished wiring the sub to the box, I proceeded to screw the sub into the enclosure. I put the screws in with a power drill at low torque and did each at opposite sides. However, after tightening them all in, I noticed that two maybe 3 screw didn’t take that well and aren’t grabbing the box, and I can basically pull one screw right out.
What should I do about this, I used 3/4 wood screws from Canadian Tire (the silver ones). The MDF board is 3/4 inch thick and the sub plus the gasket adds about 1/2 or so.
Should I just get longer screws (wider to?) -Does it matter if the screw goes threw the back side of the box at the front?
And I’m assuming some little pieces of fiber board fell through, will this harm the sub?
I didn’t think this was going to be an issue so didn’t’ really look into it, and the sub box didn’t come with hardware or a user manual, so there wasn’t any recommendations.
What type of screws is recommended? Or should I just realign the sub and plug the holes from before and make new ones? It holds tight and the sub is on it back so gravity is pulling it down but I’m not sure what’s going to happen if anything at all if they aren’t in.

I like to pre-drill before i put the screws in, this usually prevents the chipping. My advice is to drill 1/8" pilots, and then use 1" screws that are slightly wider than what you used. Does not matter if they go through the back. Another option is to drill holes for bolts and nuts.

Thanks for the help, yea i probly should've drilled pre-holes, its was a good doob..
.anyways i'll probly just get the numer 10's with 1 inch in length or whatever has the larger track. Would some silicone be a good idea on top of the screw holes just incase or does it mess with the gasket?

good coarse thread screws are drywall screws. I've used them to build a few solid sub boxes with MDF and they're not coming out. By your description, an 1" or 1 1/4" screw would probably grab better considering your gasket and sub take up 1/2" already.
