blown speaker? or something else

[jljbtm]

It sounds like the Right rear speaker vibrates or buzzes with only some low notes being played.
I'm just getting tired of it and now want to fix it. Does anyone have details on fixing or replacing this speaker? I dont know how to even access it.
Thanks Jack

I would pop the door panel and check the mounting screws. There may be a loose one. Also play some music while the door panel is off to check if the speaker is blown.

Mine just started recently. It is only on certain lows like a bass in bluegrass. I could not decide if it is the front or rear passenger side. I just figured I was blasting something too loud and blew it.
