04 WJ Limited with Infinity Sound System and aftermarket pioneer deh-11e head unit. Both front doors seem to rattle with the bass up, so today i took the panel off the passenger side and didn't find anything really. The speaker didn't look blown at all. I unplugged everything, took the speaker out, put it back in and the whole she bang.

It SEEMED like it might've helped a little bit, except that i didn't really do much. the driver's side still rattles pretty bad. the thing is, it isn't really the speaker that's rattling. It sounds like there is something IN the actual door, between the metal, not behind the panel.

I'm really confused as to what it could be. Does anyone have any idea/ have this problem as well?

 

It could be anything inside the door from the window track to the latch linkage rods.
