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?

For a quiet ride MLV is your best friend, it's heavy (1/8" thick- 1sf = 1 pound ) [I did put it on the scale and yes it's heavy] It's a really good way to block the noise.

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!

I was describing to my wife all the different layers of sound deadening material you're doing and she said it sounds like you're creating a mobil sensory deprivation chamber!

I wish! but sounds COOL ..............




and Talking about layers I just added one MORE!

Radiant Barrier

I'm putting this along the center channel and other areas after applying CLD Tiles and before CCF adn MLV, I've driving with no center console, bare metal and I can tell it gets HOT! the other day I had a Hershey chocolate about 4 inches above, and it melted!

I guess this heat going inside the cabin it's good in winter, but not good in summer, any way one more barrier to make the noisy work harder!

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.

Yeah! Sounds like a plan!

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.

One more thing about CLD Tiles... they only work if you apply them to bare metal in the middle of a flat area.

yeah, thats the plan, on the door to help keep speaker vibrations down. I'll have either an 8" midbass that throws 12mm one way, or a 6.5" midbass that goes 13mm one way. Either way there will be a lot of pressure in my doors.

If I understand correctly you are going to use the interior of the door as a woofer's box, right?

If that's the case I would add lot's of MAT specially in all the corners and on top of the CLD Tiles. It's not deadening the door any more, it's about a door to become a speaker box.

That gives me an Idea... I I could do that too! but then I need mid-rage speakers! where do I put them?

I'm going to end up begging for custom enclosures in the kick panels or up on the pillars. Should I try to make them?????

So many options, this will never end.
