Yaris Sedan Deadening and Sound system upgrade

[derickveliz2]

Ok I've spend a couple of hours every day since last Saturday.

These pictures show how I end up applying CLD Tiles to the Trunk, Quarter Panels and Rear Deck, I did put some extra RaamMat in the corners and or blocking openings in the frame.

It's amazing how solid everything feels now. (still the noise penetrates)

Then I put 1/8 CCF (foam) on the floor of the Trunk and Rear Deck, 1/4 CCF under the rear seat and wheel wells.

On top of that goes the MLV (vinyl 1lb/sf), I did put it on the floor of the Trunk under the spare wheel tire, under the Rear Seat and on one wheel well (right side) I haven't seal (with HH-66 Vinyl Cement) the overlappings between MLV layers.

Noise level is getting close to 5, I can tell the road noise from the quarter panels, rear bumper, and left wheel left. (there are no back seats)

For the air valve I end up gluing to the quarter panel cover a 6 x 14 piece of 1/4 CCF and worked great, I hear no road noise coming from that source; I can flip from circ. air and fresh air and I can't tell the difference in noise like I did before.

I also installed the main (-) ground, there was a big nut like the ones that hold the frame of the backseat. I started to run RCA cables and also installed the 3 1/2 speaker on the rear deck.

Only using the OEM radio with OEM front speakers at front and these tiny 3 1/2 speakers, I can tell that I feel the difference already, feels like my OEM stereo got an upgrade (we are not there yet)

I'm thinking on putting a DashMat like Sqcomp! I got some samples and this is what it looks like, I was thinking on putting a thin layer of 1/8 CCF to help absorb the noise from the windshield.

More soon...

So far I think I'm going to get the Black one, the Ltd Edition it's nice but reflects a lot of light (glare) I asked them for a Black sample, I show another picture once I get the new sample.

Ok, another late night for me zzzz

Worked a little bit on the left wheel well, and cut to size CCF for the Pillars, then I took some photos...

In the pictures you can see the CCF (foam) under the MLV (vinyl). In one of the photos you can see how I glue a piece of CCF to the trim panel to absorb road noise coming from the air valve.

Now I have to start gluing all the MLV together (where it overlaps) to create a good "SOUND BARRIER".

Noise level is better than yesterday, with right and left wheel wells covered.

Those lids look good mang...

I still think the best I want to do with mine is to put those factory rims on. I like the way those look. I just can't seem to find the center caps.

Nice work, It's comming along very good.

Thanks!

I love them!

when I was working on my trunk area, I punched the floor pan very hard, I can hear resonance sound that lasts quite a while but I could not determine where it comes from. So I sit in the truck(with 180lb, I thought my weight could make a little difference), but nothing changes. This is so weird. Did you guys have any experience with this?

I will keep working on this car and do some other test.

a Picture would help!

are you talking about the air valve? I'm lost here.

Frames under rear seats is back in place!
RCA cables running front to back, (+) 4g cable ready.

I took pictures will upload tomorrow. (I mean later)

Now I'm realizing / learning / experimenting that doesn't takes much to control resonance with CLD Tiles, and the use of CCF (Closed Cell Foam) to stop trim panels from rattling and the biggest and most wanted The MLV (mass loaded vinyl) barrier to keep the noise out.

Its working (o:

Pictures of the frames that support the rear seat back in place...

I had to cut and trim the MLV a little bit where the frame anchors with the chassis; the frames fit perfectly.

[derickveliz2]

The rear right door treatment...

Taking the trim panel off was hard I bet the second door will be much easier.

CLD Tiles taking care of the resonances on the flat areas of the door.

My next step is to use 3/8” cylindrical form Extruded Butyl "Rope" this is going behind the intrusion bars, I have to leave gaps for water to drain. I'll take a picture after. This will help with resonances helping CLD Tiles do thier Job.

[derickveliz2]

Ok, here is what I'm going to do! I took a photo of the trim panel put the picture in AutoCAD to scale and then traced over to get the profile of the panel. I'm printing it and then will show if it works or not, I assume there is a factor of error because the camera creates a perspective of the image, but we'll see...

These are snapshots of the process...

No work over the weekend, the weather was great so I spent time with family, it's raining now, and today's ride was good, noise coming from the rear right door (naked) but all that noise that used to come from the back when raining it's gone.

I'll try to get some thing done tonight

looks good, I hope you get enough dampening from the amount of mat you are using.

Thanks,

I only need to cover 25% at the center of flat panels to control resonance. A few CLD Tiles and the Extruded Butyl "Rope" behind the intrusion bars will take care of vibration damping, the Vinyl and the Foam will take care of the noise.

From...
www.sounddeadenershowdown.com

"After taming panel resonance with CLD Tiles, add a layer of Closed Cell Foam and a layer of Mass Loaded Vinyl Barrier to block sound. Keeps noise out and your music in."

yeah, i've read his site... it's been around a very long time. There is a difference between taming a panel, and making that panel dead. Though,... you will probably find that the most rattle in your door isn't the panel anyways, it'll be something stupid like the cable for the door handle, or the locks, or a plastic housing of some sort.

Yes I agree!
