Whoops. Do I need CCF and MLV?

I am reading about sound damping and thought I was going to apply my dealers "MESA" sound damping all of the floor and under the rear window tomorrow. More to the doors when the speakers get installed.

BUT, it seems that most threads are saying just use maybe 25% covered of this butyl / aluminum to stop vibrations, then CCF on top and finally MLV to actually block outside noise.

Will this be the best route for the floor. I figure I should just do it right the first time.

 

Pretty darn convinced of the argument of well lets say 50% coverage on floor with sound damping material. Then a CCF and MLV overtop. Oh boy, what have I got myself into.

 

That sounds not only expensive, but a lot of overkill. When I gutted my OEM JBL system, I simply Noico matted the doors, back wall, and some of the floor (and the floor was probably overkill as well). This is what I have seen most of the other Tundra owners do when doing a major stereo makeover. The biggest improvement, however was on the doors. Increased bass since all of the large ports were now covered.

 

I have concluded that to go with the full three layer is likely not going to even give the results that I'd be looking for. Well, hopefully a little sound treatment is better than none.

 

Went to test out my new HU and sound damping. I do notice the sound damping a bit. It is more like it changes the noise rather than eliminates it. I expect a big improvement when the doors are done esp. with new speakers. And, if I want to go with the CCF and MLV, the first step is done. The new head unit is a big improvement over the stock, of course. I now have a Kenwood dmx 706s.
