Started w/ installing sound deadener. Only had an hour today so I just did the rear seat area. I used MegaMat which is a 70 mil butyl. Only took about 45 minutes including pulling and reinstalling the seat cushion. After driving it around, I'm surprised at the difference just this section made. I wasn't a big believer in sound deadening material - I've had previous cars fully done in Dynamat due to sponsorships and didn't think it made that much difference. But now I'm thinking that on those cars it didn't make much difference simply because both cars were so loud already (both turbocharged running big exhausts). Looking forward to getting the rest of the car done, I've basically scheduled an hour each night to do a section due to family schedule. In two weeks, I put in the stereo, so this needs to get done before then.
