Yaris Sedan Deadening and Sound system upgrade

[talnlnky]

Derick, because of your install i'm giving the MLV a second thought. How much of a help do you really think the MLV is? I know the MLV stands for Mass loaded vinyl, does it feel heavy, like there actually is some mass to it?

In my install I basically have 2 layers of raammat on the floors, and then on the side panels & wheel wells. Then I have a layer of ensolite foam (1/8" thick). I have yet to do the front doors, and barely touched the firewall. I plan on picking up more mat for the doors & firewall, some CLD tiles for the doors (behind the speakers)... but am really considering the MLV too. I wouldn't want to drop the money, or re-gut my car to do the entire car in MLV, but I could justify doing my doors, firewall, and driver/front passenger foot area with it.

any advice. I'm all about bang for the buck, but would like a little more road noise eliminated. Would the MLV give me much of a increase in sound reduction do you think?
