Back door intake

Hello friends, when replacing the rear door coax speakers of 206m, I saw traces of dried water drops on the left rear speaker inside the door.
There is no original insulation process inside the door. How do I solve this problem? mrtttt53 2016-06-23 23:58:45

water is escaping from the glass fittings at a certain rate, hodja there is nothing to do with it.

Can you describe where you call the door water drain, where should I check?

Under the door, my teacher gets clogged with dust in time.
