mazda 3 door rattle fixed

What do you do when your Mazda 3 door is rattling for no particular reason? You buy some vibration dampening map off Amazon and get down to the business of deadening that noise. Each door that you do will take about 1 hour to pull apart add the sound dampening sheets to it, and close it all back up. Its absolutely worth doing if you have a rattle that angers you everytime that you get in the vehicle. If you plan on replacing your speakers then you should do that at this time as well so that you are attacking your projects in a synergistic manner. I learned this for the rear doors.
