Crap,
Can anyone help me out to isolate how the hell I am getting water (after a rain) in my door panel?? It appears as if a very small amount of water is coming out of the speaker grill. I have some aftermarket MBQuartz in the door, and have finally figured out why they're vibrating like they are.

Any assistance??

 

Water runs between window and rubber/felt seal on the outside. Next time you wash your car, let the water run down the windows and just watch the water drain right down into the door, especially near the sides of the windows. Most, if not all cars have same situation. Should install XTC type foam speaker cup with the bottom half cut out leaving the top half to act like a roof over your speakers. Also should apply a water repellent or sealant on your new speaker baffles if they are wood.
