Vibration from stereo bass with window down?

Hey guys, tried searching and couldnt find anything so I’m posting another question here. I’m hearing a vibration from the bass in my stereo just when the window is down. Can’t hear it when the window is up. I’m thinking it might be the weather strip? Is there an elegant solution to this? Glue it down maybe? It doesnt really seem to be attached to the door very well. Anyone else experience this?

 

I'm experiencing the same issue. I ran my fingers on the weather strip for the window and figured out when I put pressure on it the noise no longer occurs. I think that strip is just loose, and can be fixed with some sort of glue. I haven't tried anything myself yet though

 

It's not the strip itself, it's the clips that holds the weatherstrip on to the door frame. Also, it does it over bumps even with the window up sometimes. Mine does it but so far it's no big deal. I'll fix it one of these days.
