Yaris Sedan Deadening and Sound system upgrade

[cast]

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

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).

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.

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.

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

[swidd]

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.

go with Duplicolor brand... better quality. Mine is still going strong after 45,000 miles & 2.25years. I've spent probably 1,000 of those miles on dirt/gravel roads too.

if you want both looks & sound improvements... you gotta go with one of the paint on/spray on sound deadeners that comes in 5 gallon buckets for example the second skin spectrum. Everything else either won't put on enough mass, or doesn't cure hard enough.

With the duplicor brand spray can stuff (I think $8 a can) I only notice a reduction when comparing a rock flying off my tire into the wheel well at highway speeds... I notice it is slightly muffled compared to when the well was naked (pre-coating).

Look forward to it! I just slipped in the Alpine PDX-5 into the wire mess, and wholla, awesome sound! CYA!

i did 50 ft of edead 45, that got out most rattle made the doors sound much more solid when closing. I do have rattling when sub goes but i honestly dont care as long as i cant hear it inside. The thing i do care about is the front speakers being about as loud on the outside as inside. How would i go about keeping sound inside, those foam things? If all else fails i would just put speakers in the side air vents seeing they point at me, i would get the most sound per volume setting.

Some where I read... "MLV keeps the noise out and the music in"

I'll let you know once I get my system running.

thanks. Everytime i roll up to a stop light or in traffic, i tend to turn my music down and its not even loud just its as sound outside as it is inside. Im paranoid like that dont want to disturb people with my awesome Eurobeat collection

btw, Eurobeat is pure JDM

A layer of mat all over the inside of the door will help a lot. It'll dampen most of the midrange and midbass tones. You'll still hear the treble/vocals fairly well tho.

The best option if you don't want any sound to exit the car is to make fiberglass kickpods to install your speakers by your feet. It has the added benefit of allowing you to aim your speakers for better SQ too.

In my mazda I had it so that you could have music at about 130dB on the inside, and barely hear it outside of the car... if I cranked it much more then the bass finally would overcome the amount of mat I had... but even then, it wasn't nasty rattle like most people's cars do.

[ezhacker1]

I probably look into what i can fit in the side air vents, or maybe the middle vent which i deem pretty useless for aiming air.

[derickveliz2]

Ok, I've been reading and reading all about car audio and passive and active crossovers, and I think I'm getting an idea, thanks to sqcomp and talnlnky for all your help and information. This website it's a very good source of information: http://www.bcae1.com/

I'm done with my son's playset so this week I'm going back to my project.

I'll post some ideas of my audio set up and progress with the deadening process.

Thanks YarisWorld.com!

That's what this forum is all about mang! I'd like to hear your ideas...
