I did a little experiment on the left front wheel well... I put almost 3 layers of MAT and called done! I drove for 3 days like this then I put the MLV on top! WOW! the noise was gone!

I've been searching around and I see all kids of cars go with MLV to make their cars less noisy, (BMW, AUDI, other TOYOTAS and many more) MLV may not be as good as 3 or 4 layer of MATT when the GOAL is SPL, but for a quiet drive blocking external noise in the FIREWALL, DOORS and FLOORS is really GOOD

In architecture/construction we use it a lot, when using Lead is not possible to make sound barriers.

Using all 3 layers (1.-MAT or CLD Tiles = control resonances, 2.- CCF = Absorb high frequency noise and cushion rattles, 3.- MLV=Sound Barrier) makes this system work really good.

It's like using the right tool for the job

MY 2 cts. if I had to do it again, I would do it exactly the same way!

Ok... Looks like i'll be buying some MLV in the future. Thanks.
40sq ft of MLV, bout 4-6 CLD's, and another 40-60sq ft of mat and I should be done

EDIT: I'm actually contemplating foregoing any mat on the firewall, and just doing MLV alone.
40sq ft of MLV Then around 25sq ft of mat, and 4 CLD's. that would really cut my costs. I'd be down to around $150, before I was over $200.
