I never get my interior done at any place. The guy who drives the car from the wash line to the drying area always seems to spray all the windows from the drivers seat. Overspray everywhere and the shit is running down inside your door (speakers) while he's driving it to the drying area. Then it might sit a little while longer waiting to be dried. I've asked the facility to not do that and they say no problem, but it only lasts once and they're back to soaking everything. I would love to get my interior done, but perhaps I'm just anal. Or, maybe it's just because my speakers are really expensive.

Now, just to make this post a little longer: If your interior seal at the window is tight, then the liquid runs down your door panel and still can get to the speaker...
