Congrats! Patience of a saint to have tackled that huge chore.Finally had a chance to finish my sound deadening project. Today I installed mass loaded vinyl (MLV) on the floor. Toyota did not put 1 inch of any sound deadening on the roof, doors, rear wall, or hood. I installed sound deadening in those areas and had already posted pictures on this thread. Toyota did put a small amount on the floor but it was not nearly enough. After removing the front and rear seats along with the center console I was ready to tackle the hard work. The first picture shows the carpet removed with just the carpet pad on the floor which will decouple the MLV making it more effective. The second picture shows the layer of MLV which goes between the carpet pad and carpet. I still had to cut holes for the bolt holes, wiring harness, and floor duct and then put everything back together. I did a quick test drive and it did make a difference.
