I got it last night, I found the clip as your said and pulled it out with a flathead screwdriver. I got both rear speakers in, but one speaker screw on the right door stripped out. They sound good although highs are muffled compared to when the doors are off. The 4 ways for the front come in friday.
At bestbuy in the bay we keep short and long "fatty" screws, usually fix that stripped out issue, or you could get a "speed clip" which is a clip with a slight threading that might work for you as well, Small amounts like that I usually just give over, some ppl might be stupid and charge you a small amount depending on the installer and there mood.....
