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.
