im looking to dynamat my whole rear and around the speakers. ive never listened to a car that had dynamat in it. im just wondering if ill notice a huge difference? right now, my stuff doesnt rattle too bad unless i pump it up real loud.

my setup consists of rockford power interior speakers and a 12in power acoustiks sub and amp all in my hatch

the biggest difference I noticed in the rear and front of my coupe was a cleaner sound, more controlled, and the rattle ended entirely.

did you just use the speaker pieces? cause im thinking of doing my whole trunk with that stuff and around the speakers.

It’s pretty much like adding an intake – you will notice a slight difference most likely.

I noticed a big diff,and I just did my trunk door and just some places that were rattling.It doesn't let too much pressure escape,so it sounded more uniform too me.And it really helped the noise from outside.good luck.

I have two left over small peices on the trunk... but it never rattled, I did the entire rear speaker deck... (this most noticably eliminated its rattle from speakers, and also increased clarity at high volume, probably due to less mount vibrations) I also did all around the front speakers and even on the plastic rain cup on the door panel (yet again, rattle gone, and a little better clarity, but not too much.. If you cover the rain openings, it will loose volume, im currently going to try editing it, and increasing the open space in that cup, and make a custom rain cover, so it has more air flow)
