I decided it's time to replace my gross carpet (prev owner smoked) with a new OEM one, and do some sound deadening! I've done a lot of reading of previous posts and on Google. From what I gather so far, the recommendation is generally 3 stages. I saw that carbuilders have a great kit but they're completely out of stock and the US distributor doesn't know when they'll be available here in the states.
- Stage 1 = damping. From what I can tell, butyl-based products are the move here. I'm looking at going with kilmat for this base layer
- Stage 2 = blocking airborne sound waves. I see that typically people put MLV, closed cell foam, or some combo on top. I like that the carbuilders kit is a combo of closed cell foam and MLV. I don't know what to use here
- Stage 3 = absorbing any other waves. I see sometimes people use open cell foam.
- What should I use for stage 2? Any product recs?
- Can I use the same thing for stage 2 across the entire floor, or should I use something else for the cargo area?
- Do I need a stage 3?
