2008 Yaris sedan ‘S’ sound deadening project.

That's awesome Herb. Although, I'm not sure how I would feel about the louder exhaust reading (I do want my exhaust louder tho, lol). I wonder how different my system (just a JVC HU and a Type R sub) will sound compared to yours. hehehe.

Hey Herb,

Maybe it's a guitar effect?

Or the meter it's bad?

It's true... you can hear/feel the difference, but it could be just another level/frequency of resonance inside the car that resonates different from the outside noise.



You have taken care of some of the resonance of the sheet metal panels of your car by applying Mat and Ensolite, now it's like a big speaker to the inside, what you may need now it's a "Noise Barrier" AKA Mass Loaded Vinyl (MLV).

Send me that meter and I'll give it a try in my car.

Thanks man. I decided I'm not going to waste a lot of thought processes on it. I'm VERY HAPPY with everything, so to heck with the reading.

We need to meet up again soon. I've never heard your system, it would be fun to do a comparison.

I'm thinking your "Noise Barrier" suggestion is probably hitting the nail on head along with another level/frequency inside the car. Weird. Again, I'm not going to worry about it! If you really want to try the meter on your project, send me a PM with your mailing address info (home or work) and I'll send it to you. Just send it back when you're done.

Herb, take a look at this, you are not alone!...

Thanks! I read through most, not all of the posts, and I feel better! So it's not just me! I got your PM (I was gone camping the last several days), do you still want me to send you my little digital meter based upon that link? Either way, it doesn't matter to me.

Yeah, lets give it a try...

[Herbicidal]

I've got the perfect box. I'll wrap it up and try to stop by the Post Office tomorrow on my way home from work.

As part of my sound deadening project, I'm looking to add some CLD tiles to the roof..Anyone have tips/experience removing the roof liner? I'm a little nervous, as it seems more delicate than lifting up the carpet/trim pieces!

I believe that SQComp has done his headliner. He has a HUGE thread going on in this same forum section. I don't have the exact page, but I thought he did it about 2 months ago? I'm thinking about doing my roof too, but for now, I'm just enjoying my car!

[derickveliz2]

Look in here

http://www.yarisworld.com/forums/sho...ound+deadening

it's big and lots of information.

I'm going to apply at least 6 CLD tiles to the roof too. SOON!

I will post it here:

SQcomp had a big hassle with his headliner because of the side curtain airbags & sensors in the way. If you have an older modle (I think pre-2010, maybe pre-2009) you shouldn't have the curtain airbags unless you bought a special package or upgrade.

If you don't have the curtain bags, just go slowly, if you do have them, you may think hard about going to a stereo shop and having them install the CLD's for you... you'll pay a ton for labor charges i'm sure, but if they mess up they have to cover it.

The package is on it's way! The Post Office estimated 2-3 days for delivery.

I finally mounted the grill cover to the subwoofer enclosure. Some people may not care for it, but it amuses me to no end!


This is the final postion of the subwoofer in the trunk, still plenty of space. I never used the pass-through for anything, so blocking it with the sub is no biggie:

[toy_toronto]

personally, i love that sub grill cover.

[Herbicidal]

Update: after nearly 3 months since I completed this project, everything is still working flawlessly! No burned out fuses, nothing rattling, no nothing! The only thing is that I need to secure that sub box in the back! It keeps sliding around due to my...errr...exuberant cornering. I picked up some heavy duty Velcro that I just need to take 5 minutes and apply. Then that should be that.

I do want to replace the stock HU at some point, so in the meantime, I think I will order that Toyota replacement HU bezel to allow an aftermarket HU to fit.

[derickveliz2]

Looking forward to see it.
hey how are the rear spring stiffeners doing?

D.

[Herbicidal]

I haven't checked since I put them in. I'll have to look this weekend. At the time, they raised the back end by 1/4". Honestly, I haven't really noticed a difference in the ride. I think a 1/3" to a 1/2" thick, circular, flat spacer directly under the rear springs would lift the rear of the car up by that much without affecting the spring rate.

[derickveliz2]

I know what you mean, it's very relative to the TRD springs you have compare to the NF210s I have. But take them out, and then you will feel the difference.
