It may not be the subs themselves. I was getting a good bit of rattle; did some searching here and elsewhere, and wound up pulling the back deck, and adding some foam and double-sided tape between the metal decking and the insulation layer that goes on top of it. The insulation has a paper backing of some kind that lays against the metal, and over time I think it has hardened or become less flexible, and it rattles/flaps against the metal depending what kind of music is playing.
After adding the tape and foam here and there, the rattle is gone for now. No idea how long this fix will keep but for now I'm pretty pleased. YMMV.
