ok, all i have right now is a pioneer cd deck and stock speakers...i have a 95' civic dx, and when i turn on the bass, something starts to rattle on the driver side door, i tried checking it, but i can't find what it is...i think it's something inside the door but i can't get it to open, anyone have any idea's on how to fix this? i know it's something loose, but what???

 

The only way is to pull off the door cover, and listen. I could be anything in there.
