Yaris Sedan Deadening and Sound system upgrade

[derickveliz2]

It's hard to have a sense of scale with db (decibels) so I thought about what if I open the window at 80mph? almost 10 db more, but to my ears it was twice as much louder. It's interesting how these measurements work, we are used to grab a ruler and measure, but with decibels I guess it doesn't work the same way.

the dB scale is exponential. either 0 or 1 dB is supposed to be the lowest volume of sound a human ear is supposed to be able to hear. Every increase of 3dB is technically a doubling in volume. HOWEVER, human ears suck as listening tools. Human ears usually perceive a 6 to 10dB increase as being a doubling in sound.

So, you saying that a 10dB increase felt like a doubling is within normal perception.

Also, once you start getting up past 120dB, the ears really can't tell what a doubling is... especially when you start getting in the 140+ range.

Another thing, there are many different decibel measurement tools out there. I know of only one that is accurate & consistent regardless of environmental conditions. Many are very liberal with their ratings (higher readings than they should be).

Thanks Taln, I know that there is a logic explanation for all that. and I agree human ears are not a very good listening tool; and yes the meter I'm using is from Herb, and it's not very expensive (around $35) so we are kind of playing and having fun, not actually getting real results.

I just wanted to give it a try, since he was a little frustrated with his before and after readings, but my conclusion besides it's a cheap meter, he is looking at MAX recorded and like if you watch in the videos the numbers kick up and down at some points, so I'm pretty sure his treatment is working well.

I'm going to send the meter back to Herb next week so he can play with it again.

2 nights ago, I met a big nightmare! putting back the center console was a pain!!! but now it's very tight and snug.

So when ever you do your deadening project remember to leave space and plan ahead on what you cover, for your trim panels, screws, seats, etc, since adding Mat, Ensolite or CLD Tiles, CCFoam and MLV like in my case, you will increase the thickness of your floor, so everything is going to be tight.

For the back panel of the center console that has the cup holder for the rear seats, I'm going to have to shave on the bottom to make it fit properly.


but you know what... it's worth it!

Last night I removed the OEM head unit, and it was a 30 minute workout very easy to do. removing the vents from it with... those 8 clips, where the time consuming part. Now my interior looks really bad, and without a radio to listen, I really want to install my system; this should make me move faster on the installation.

WE HAVE POWER!

I did the BIG 3 and installed the power cable for the amps too.
Took me 1 hour and 45 minutes from start to end, including cleaning and everything.
This thing about the battery-cables-alternator scare the $.... out of me, so I took my time and planed everything ahead.

My lack of knowledge about electricity makes me wonder but I can tell that my car had a very basic installation, cables are very thing and flimsy so this thing about the Big 3 it's a must.

So far so good, the car started like every day and nothing went bad, besides my clock got behind a few minutes and for some reason, I'm not sure but in idle starting from a stop I hear a very little whistle / whisper noise very similar to the one you get in your speakers (note: there are no speakers). As soon as the car starts moving it disappears, It could have been there before but I just never payed attention to it. It's very soft.

I'll take a photo as soon the rain/drizzle stops.

I hope everything is OK!

I want to do this, but I'm afraid of killing myself or the car. So, I wonder if they do this at audio shops?

You can do it! Just disconnect the battery and remove all the *bling* from your body first. Don't want to short something out.

Of course they do this at audio shops...

Give me 30 minutes and I'll have you all 1/0 G and techflexed with heat shrink.

DERICK! WTF are you doing?!? Hide those ballasts and trim that flex with a hot knife at least! :D

So you noticed I'm running HID's JeJe! (4 of them)

I'm sorry to be so naive, what is "that Flex"? is the black thin layer covering the wire?

So now I understand... if something takes you 30 minutes it would take me 3.5 times more (small detail)

So I got my self a Stinger distribution block 1 to 3 and some Maxi fuses (20,30,40) for (+)

and for (-) I'm going to use the 2 kicker distribution blocks (1 to 2) that came with the amp wiring kit. or I think it would be better if I can get direct ground connection for each amp; we'll see.

I have to build a shed this weekend and prepare for a big trip next week so I'll be disconnected from Yaris World until next Friday.

See you then!
