help, buzz when sub plays

Ok well when my sub is in the box there is this buzz coming (seems to be coming from inside the box). Well i figured out that when it hits, air is coming out of the speaker terminal cups (plastic things). They are siliconed inside the box, but the air isnt coming out from the edges, its coming out from the actual place where the speaker wire goes in, know what i mean?
how can i seal this up? should i use hot glue, or silicone, or what? And if air was leaking out of the cups, would that cause a noise inside the box? how?
thanks

well i took the sub out and nothing was in there, and there wasnt anything loose.
but when i put my hands over the terminal cups real tight the buzz goes away.

the terminal cups i use have the male connector that goes inside the box actually bolted on to the cup. they are held on with a little maybe 6mm nut. Could those be loose?...just somethin to think about

something may be broke inside the terminal cups, my one box did that, i took it back. if you need to, take it out and get a new one from radio shack.
terminal cup that is

Another reason why NOT to use terminal cups. Just an added expense thats weak.
Remove cup, throw in trash. Plug end with proper size wood. Drill hole, run speaker wire through. Silicone up hole so air does not leak.
If the box is sealed and is sealed properly you should be able to puch the sub and barely have an air leak if any at all.

you think that will hold ryan? what would i do for the block? this is what i was thinking:
cut out the block so it fits snugly...liquid nail all around the edge (the top and bottom and sides of the edge) and then slide it in..then once it's in firmly, run a bead of silicone around the line where it wouldve been cutout (sorry this is hard to understand, i dont have the right terms to use)
would this hold? the pressure wouldnt contact this weakest pointi n the box and push the little block out? thanks

Make the block a little larger than the cutout area.
Liquid Nail in place. Use a few small nails to hold it. Apply weight on it.
Do this on the inside of the box.
I never use the terminal cups. Just another thing to go wrong and added expense. Just leave the speaker wire long enough :)
