Hello, I have a question. My speaker in the back (behind passenger side) rattles when any song comes on that uses base like rap, I usually ride with the windows down and I need to turn the system up a bit, even if I turn the base all the way off it rattles. So just an hour ago i got in the back seat and pulled off the black plastic just enough so I can stick my hand in there, I lightly held and pressed down on the rattling speaker, and it stopped rattling and played beautifly, but when I let go, rattling AGAIN. I tried being ghetto by putting tape on it but that didnt work, any other ways?
