I want to soundproof my Mazda5 but I don't want to break the bank! None of the options I've seen have convinced me so I'm thinking of using 4mm thick cork sheets and 2mm on the doors! Any thoughts?
What is the size of your bank? As KW_DA said, you will need to get something like Noico or Kilmat, etc. I just did my doors with Noico 80 mil sound deadening with Noico Red 150 isolation materials. The front doors are a PITA. Well, all doors are a major PITA. On the front, at least, you can remove a bunch of garbage that was put on at the factory. On all doors, it is almost impossible to get to bare sheetmetal. There are some pockets where you can sneak some material through. Mazda bolted on a huge plastic part to which all the cabling and window motor is attached. Not worth the time to remove it. Also, especially with regards to the rear doors and rear trunk panels, the fit between them and the sheetmetal is very tight. On the rear doors I only applied 80 mil and 150 Red to the door card. The trunk is probably the simplest of all things to do. I have not done the floors or ceiling yet. However, I do not know how much it will all help. The engine is just loud and glass is way too thin. The best thing you can do is get nice (and quiet) tires and crank up the volumeI want to soundproof my Mazda5 but I don't want to break the bank!
