So, I'm replacing my rear bose speakers with some infinity kappa 2 ways. Installation is proceeding at my usual pace (casual), and I've managed to not loose any parts so far. In fact, I've found parts that none of f the how-to's around here mention. The parts in question are 4 black metal clips that fell off the rear deck plastics when I pulled them free. (2 clips per panel). I spent about half an hour trying to figure out where the hell they go and I still have no clue. maybe someone else will.

 

Got it. nevermind.

 

Those clips go onto two little raised areas on the plastic grilles. They are raised up so the top part of the metal clips to clip onto and then they go into holes in the rear deck. I know its not the best description but hopefully it will help. I will take some pictures of where they go tomorrow if you can't figure it out by then.
