They are snapped in, its the little flappers all making the noise.

I had to look up Tesa tape, but that seems like a reasonable idea. Looks tedious to get them out and back in...but I suppose it will be worth it. Thank you.

So the 2 vents behind the seat rattle like crazy when the subs are doing their thing. I don't want to just block them. With all the different systems installed in the trucks someone must have a fix/workaround for this issue. Suggestions appreciated!
