Speaker/Door rattle or vibration from rear?

[Mossyoakglock]

I am having a strange vibration coming from what I think is the rear passenger door, it could be the front passenger but not 100% sure. It only happens at certain bass notes or when an announcer or commercial comes on with somebody that has a deeper voice.

 

I haven’t taken the door panel off or checked to make sure all screws and fasteners are tight but does anybody have any thoughts? It drives me crazy.

 

I’ve got a rattle/squeak on the dash on the right side that I’m going to put some felt on to stop that so maybe that is the problem.

 

I’m going to try to take the panel off this weekend and check around. Any suggestions for ways to stop the vibration?

When my old stock speakers decided to completely separate from the basket, they also rattled in bass. All you Ned to do.is remove your door panel of suspecting rattle and look at the speaker.

Could be the plastic door locks. Mine did the exact same thing. I added a piece of velcro (fuzzy piece) and stuck it between the door panel and lock plastic. Seemed to cure that rattle, but I find these trucks are rattle boxes from the factory. I have a rattle coming from the defrost vents that I havnt solved yet.

Don't know if you found anything or not but I've been working on this problem with mine. Even went out and bought new speakers because I thought they were blown.

 

I believe the problem is the sytrofoam sound deadener / insulator behind the door panel. It is a rigid styrofoam and is vibrating against the door / or panel on certain bass notes.

It drives me crazy. I put some truck cap tap in there and it helped a little but it's still there and very annoying. I think the ultimate solution is to replace it with something else. I saw a dynamat product in another thread, I might check that out.
