Just did my drivers side door. I noticed this window bottomed out on the door. Who ever upgraded the speaker only installed one screw to hold it in place so I added three more. I also covered all the door handle and lock rods with vacuum hose to quiet them down. My door handle was also loose causing a rattle. It is held on by two sheet metal nuts which needed to be tightened. I noticed a difference in sound just when I close the door now but I haven't had a chance to take it for a ride with the windows down because of all this rain lately.
