I didn't think of it myself, but I liked the idea enough to steal it. My interior isn't too bad, but I want to make it better. I'm replacing my door panels with diamond plate aluminum. I already got rid of the ghetto speakers that the previous owner hacked into the lower door panels and put in kickpanel components. I've decided to cover everything in B-Quiet Ultimate which is a little cheaper than Dynamat and I've heard a lot better things about it. I've ordered it, but it hasn't come in yet, but that's alright. I haven't had time to mount the panels anyway.
