So this weekend I attempted to install sound proofing and my door speakers. I added material to the inside of the door and also near the speaker. The problem I have now is my door locks sound funny when it locks. It sounds like something is loose but man I cant tell what it could be. Again I just added sound proof material and didn't mess with anything else. Kind of upset now as I have a few more rattles after removing the doors. I even took the doors off again and make sure that nothing was impleading the seal of the door. Seems like the doors don't fit as tight as before I removed them, but its close. I guess I am just real picky. Anyone have any idea what it could be on the lock sound?
