As some may know I have replaced all of my stock speakers. I had thought that the front passenger side was rattling from not being mounted well so today I modified to stock speaker/bracket to hold my new ones and reinstalled them. Turns out that this was not the cause of the problem. After closer inspection it is actually the window crank that is rattling. I plan on converting to power windows next yr which will correct the issue but what can i do until then? Will putting dynamat on the doors fix this?
