Went in search of mysterious rattle that's driving me nuts. Tore left front door trim off, tightened all screws holding speakers in place, took right front door off and lo and behold speaker no longer attached to door! :-/ Reattached speaker then moved onto right rear door. Took trim off and there is no speaker! Reattached and went to left rear door and there is a speaker there! **** one but a speaker none the less. Reattached trim and went hmmm, back passenger seat doesn't feel stable. Wasn't even sitting on it's mounting rails. Unbolted it, set it on it's rails so hopefully have eliminated a s**t load of annoyingness.
