So my next step is to apply sound deadener and insulation. I bought 62 sq ft of RaamMat for $80 (butyl based) and then i got 40 sq ft of dynamat on ebay for $40. After receiving the dynamat, i'm wondering if I actually got the sound deadener, or the in1/4" insulation? What does this look like to you guys?

 

we market our foam pad as a under carpet sound deadner.Not as dense as the butyl based deadner but still good

 

I was going to save my RaamMat for the floors and doors.. Basically I should get some adhesive and roll the dynaliner in the trunk and call it a day huh?

 

You should look into Fatmat. Inexpensive and the same as Dynamat.
