A long while back I made a thread about the overall sound system (turns out the lil kickers in the back I have are actually worth just keeping there, who would've guessed?). Anyway; I've noticed that my subs went and knocked the passenger side speaker cover loose enough to rattle annoyingly (to me anyway). The driver side one sticks down pretty hard, but it's lil buddy is loose towards the door.

I'm thinking of ways to pin it down to reduce the rattle, but i'm not getting any good ideas! I'm starting to get those weird stupid ones (like cut a hole and put a tight zip tie!). I imagine taking the entire back cover off is going to be in my future; but I was wondering if anyone ran into this specific problem (did a search, this is just a tad too specific to seemingly get it's own thread from anyone)

Any ideas or help is greatly appreciated.

[EDIT: It's a 96 accord EX...sorry for being a tard...though I think most of the covers are the same)
