Ummm what are these for?

that noise did go away, there's still tons of rattle back there but you can definitely tell that that one is gone.

I had to put double sided tape on my license plate to stop some of the rattle.

license plate rattle is definitely a problem. all the interior trim is "loose" in the car too like clip tight and helpin place but sort of springy. that would rattle too.

I might have to do the double sided trick on my license plate too. I haven't done it yet since I'm still deciding if I want a CF plate frame or not (real cf) or any plate frame for that matter. Haven't put one on since painting it, and kind of like it since I noticed less rattling without one...

Put the volume louder, problem solved lol

Weather stripping + I'm thinking about drilling 2 holes for the bottom of the plate. Why Chevy didn't just make 4 holes...idk

I did rake out all of the trunk lining and duct tape some things down, a guy at the place I got the system installed said it looks like my heat shield for my muffler is rattling, he suggested just getting the entire car Dynamat'ed lol.

Also it really sounds like the taillights rattle too, sigh.
And idk if this matters but my box has one sub facing the inside right of the trunk and the other left. Not sure if having them face toward the back seats or towards the trunk door would reduce rattles.

I dynamated the front doors completely and some of the rear doors (the large openings) and it sure did make a difference. I don't hear my exhaust in the car as much anymore, and I'm sure more sound from my sound system stays in the car (I can't say because it all got installed on the same day, so I didn't have a chance to have just the sound system, not the dynamat. But the exhaust sure got quieter inside the car.

And the guy who installed mine suggested that sub (or subs in your case) should be facing out towards the hatch with the setting set to "REV" instead of "NORM" for the sub... Where it reverses the pound of bass to go in the same direction as sound of speakers... If that makes sense. Well, I did, and the bass does sound better now.

Nice lol.
how much did your Dynamat cost?
I drive an Aveo sedan and I think I'd have to get the entire trunk space Dynamat'ed.
I tried the "Rev" setting, it does sound better, but I don't feel the bump as well.
Here's my box, really wish i would of gotten something different lol.

I know, but for me I'll take the better quality sound over the bump. Plus bump gets old very quickly... You want a little softer base over time (at least for me)...
