Thanks.

I upgraded speakers in Challenger and with better bass comes a little vibration in the rear package tray. It's installed correctly, just rattling/vibrating over and behind the sub. I placed a small piece of rubber between the tray and the rear window and that helped some but on some notes still getting the rattle. Any easy fixes here?

I've put Stinger Roadkill on the metal tray. The noise seems to be between the window and the fiberboard tray, not the tray and the metal underneath. Either that or it's vibrating on top of the speaker itself.
