2 part super glue?

its C.A. (catalyst) glue you can find it at any hobby shop. they make two types that ive used in audio instalation. one is good for just about anything and the other os for foam rubber (works good for doing re-cones) they run between $5 and $10 each.

oh and just a tip when using it make sure your fingers dont have glue on them when you spray the catalyst, you will bond to what you touch lol.
