Do It Right The First Time
Crutchfield Customer Review (What's this?)
I just took possession of my new 2016 Ford Transit Connect Cargo Van that I use for film production. I immediately installed Dynamat Extreme and Dynaliner throughout the entire interior. I created templates for every single cut in advance. The templates helped to dramatically speed up the installation process and reduce waste to virtually nil. Because the van is painted black, I also opted to use 1/2" Dynaliner on the roof to reduce thermal heat transfer. I used 1/4" Dynaliner on all the metal body panels and body cavities (over Dynamat) and used 1/8" Dynaliner (over Dynamat) on the front driver and passenger doors behind the door panels. While I primarily used the Dynaliner to make the interior a little bit cooler during the summer months, I was impressed at how much it assisted in aiding additional sound deadening, a noticeable difference over just Dynamat alone. I also installed Dynamat and 1/8" Dynaliner on the back side of the metal bulkhead to stop an annoying vibration noise. I taped every seam and edge with Dyna Tape to prevent butyl seepage on my film gear and cases. The only two pieces of equipment that made the job easier was a tennis ball (for medium curved radiuses) and a hard plastic curved fruit peeler (for small tight radiuses). Bargain hunters beware: Dynamat only warranties their products when purchased through authorized dealers. They don't sell their products on Amazon. Don't get taken by knock off products on the gray market.
Pros: This is the best system to reduce road and engine noise in your vehicle. It is a seamless system that makes installation a breeze. If you can afford it, go with both Dynamat Extreme covered by Dynaliner. Together, they offer great sound deadening and they provide the added benefit of reducing thermal transfer of heat in the summer months.
Cons: The only con is the additional weight of the products if you are using these in a street or track racing vehicle. For a daily driver, that is inconsequential. Must be installed in a warm climate.
