Yaris Sedan Deadening and Sound system upgrade

[cast]

You've got this result by only deadening the floor? Did you deaden the doors?

Thanks.

I'm very happy with the Yaris now. Completely quiet, all I can hear while driving is the sound of the wind against the windshield, and even that's pretty silent. The tire noise from driving on old rugged asphalt doesn't make it into the cabin at all (or my hearing is fading with age).

Its so quiet that the only annoyances that remain, is the sound coming from my key chain vibrating gently... and a new rattle from the rear middle seat belt assembly. I tried to make it shut up, but something internal to the seat belt roller is resonating, making rattle. I covered it in bed sheets and such, so the sound doesn't really go anywhere.

In short, I deadened everything except the ceiling. Everything was very easy to get to, once I took the seats out.

Approximately sorted by the most effective/giving greatest immediate result:
Doors (huge difference)
Side walls next to rear seats. (large surface of sheet metal)
Lower trunk area below the spare tire. This has thin sheet metal that vibrates.
Floors below and in front of foot area (including wheel wells, made a huge difference in engine sound)
Hatch (foam)
Rear wheel wells (deadener)
Rear floor under rear seats and foot area (this area has fairly solid metal and no thin sheet metal that vibrates, no big effect).
Center gear shifter area has some open sheet metal that vibrates quite a bit, helps to cover this.

50 sq ft B-Quiet $134
50 sq ft e-Dead $65
Interior carpet roll $10 at Kmart, $15 at Auto Zone (exact same roll)

e-dead is not near as good as B-Quiet. B-Quiet is better than Dynamat.

All in all very cheap DIY to create comfort.

That is about 100 SF, I got 67.5 ft² of MLV, and I'm running low for the floor and firewall, I just ordered another 25 SF, with a total of about 92 SF, so it's about right what it needs to cover a Yaris Sedan.

I'm sorry if I'm been so naive here, what would be the best orientation for tweeters from the images below...

Thank you!

That depends on your axis response of the tweeters. Personally, either of those two, I'd probably do the first one. But you really have to hear the results to decide the aiming.

Where are your mids, in the doors? What is your crossover slope and frequency at?

Yeah! Dynamat sucks compared to B-Quiet!

I have mine like the one's shown in example B , I'm fixin to remount them flat to see what type of result i can get.

Thanks for the infor.

Did you use any rubber mat or mass loaded vinyl to cover the floor?

Yep. I've got 3 sq ft left, that I'm saving for the mirror, and whatever else begins to vibrate once I get some SPL... license plate maybe. So yeah, 97 sq ft in the car. Its only ~28 lbs... about the weight of the spare wheel, half of the back seat or the weight I lost in the gym in the past few months.

I hear your call for pictures, but it all looks stock. I like the way the Yaris looks!! I made a little video instead, but like I said, it doesn't show anything because I put it all together again. I'll keep in mind to take pictures if I disassemble something in the future...

B-Quiet on the floor and lower front firewall... Rubber butyl mat with aluminum foil backing. Very effective, and very easy to work with. A single layer was plenty of added mass on most places.

The cheapest material out there, eDead_45, was not near as effective (if much at all...), the glue was not 'permanent', very minimum mass. It was too thin. But it was extremely clean and easy to apply, and being super cheap, I used it for double and triple layers in the trunk and under the rear seats (large horizontal surfaces).

How did you deaden the doors? I assume that you used B-Quiet? Did you use other material?

OK, I'm going to put everything together before installing Tweeters! and test them

OK, I'm clue less here, how do I found this out, I got the same components as _SeVeN_ (HIFONICS ZXi6.5C ZEUS 6.5") http://www.yarisworld.com/forums/showthread.php?t=26407

swidd...

What kind of rubberized coating did you use in your wheel wells and how did you do it?

Thanks

Yep. B-Quiet, about 15 sq ft per door, double layers in the middle/most vibrating areas. Then I stuffed closed cell foam mattress material in the bottom, behind the speaker, and generally all around. And that was it.

I did not do anything to replace the moisture barrier, because when I opened the door I did not see any evidence of water having ever leaked in there. It was all clean and dry. - After 62,000 miles with harsh winter weather!

I also didn't do anything with the plastic door panel itself, other than replacing broken clips/fasteners with new ones (box of 30 cost $15 in a local upholstery store). The plastic didn't seem to vibrate when I had sound coming out of the door speaker.

Uh, $5 bottle of 3M rubberized undercoating spray from Walmart. Tried to spray it myself, but it got real messy, so I took it to one of those drive thru oil change places, bought a tire rotation, and asked if I could apply the rubber coating while they had the tires off. Instead they did the spraying for me, I kept my hands clean, and then I didn't have any cash to tip them.

Cool!

I'm thinking of Spectrum sludge

Not cheap, but still going to dig in and learn more of it's properties and pros & cons; Spectrum Sludge is from Second Skin Audio.

BTW, I started building my son's playset...

This is not going to be easy

I did the undercoating way back before much else, and did not notice much improvement if any.

It did make the wheel wells look better though. All black and deep, hiding the cheap plastic and thin metal... But it wears off after a while.
