Our vans are awesome... and noisy. The sound system is actually pretty solid, but hit the road and you're met with a lot of road noise, wind noise and misc. noisey noises. I decided to attempt a remedy. Based on the expertise of Don at sounddeadenershowdown.com, I purchased CLD and rolls of CCF and MLV. Google or go to his site to decipher that alphabet soup if you're not already savvy on the topic.
First, I removed basically the entire interior. Seats and all. What I noticed is little to no factory sound deadening materials used. Either sparce or entirely non-existent:
The interior is extremely easy to remove. Very few tricks required. The headliner I did leave in place until time to do the roof because of all the wiring secured to it. Decided it would just let it hang down a bit when the time came to work up there.
Next, I put CLD (Stinger Road Kill Expert) on flat unsupported sheet metal sections I figured were prone to vibration. Don at SDS recommends 25% coverage. All too often you see excess amount of CLD (Dynamat) use for little to no gain.
