Hey everyone, I'm putting some much needed sound insulation in my insight today. But I noticed that it appears that the floor already has some kind of oem sound insulation on it. At least that's what I think it might be. It looks like it's made of asphalt and is hard as hell to get off, basically impossible. I know you cant stack sound insulation so I was wondering if anyone knows if that's what this is? Thanks -Eli

Wait why can't you stack? When I did the sound insulation in my turbo insight, I just slapped mine over whatever that stuff is. Haven't had an issue at all.

+1. Stacking is exactly what many places will do if a customer wants more deadening than a single layer of Dynamat or lizard skin spray-on.

Take some time to research the different types of sound control to get the most out of it while you're in there. Soundproofing Principles

Because google says so lol. They say that stacking is a myth, but putting deadening foam ontop of the butnyl rubber is good. Sorry for the late replies
