Default Rattle with JL Sub in Trunk

After install the JL sub woofer + sound damping in the trunk, I was able to remove most of the rattles. But there is one specific part within the trunk, I have no idea how to eliminate the rattle (the paper rattles).

I have confirmed there is rattle by touching the outside of the part highlighted. It happens on both side of the car.

Are you highlighting the cabin vents?
If so then you are moving enough air with the subwoofers to cause the vents to try to expel it assuming it only happens with the truck closed.

on the other side of those vents, are rubber flaps. When my subwoofer was installed, i noticed the same "paper" sound flap.

I removed my bumper to remove the rubber flaps (one on each side). no more paper flapping noise. only drawback is dust can get in I think.

do you hear the rattle on the inside of the car or out when playing music?

Yes that's the vent. The subwoofer causes the paper to vibrates on both sides. You can easily hear it under certain songs.
