Yaris Sedan Deadening and Sound system upgrade

[sqcomp]

The other nice thing about this kick pod setup for me is that I can have the car wide open and the sound stage stays the same...good for quick demos.

With what I'm doing, I'll need the flexibility that the Bit One gives me. The nice thing though, is if anything bad happens to the piece, I have the source to use.

Yes, I've given up the spare tire. I've got roadside assistance from three places (insurance, Toyota, and the tire place). I'm good.

I think the next pictures will be the finish of the kicks, more work on the sub enclosure, and sometime in the next month, I'll be working the frame for the amps. I'll be using one of the shop guy's cars while the Yaris is being welded on. After the frame is up, then we place the amps and the Bit One.

Fun!

^ That is a jig...I now make two copies and flush them down into my grills...

You'll see those soon.

Very nice!

I keep staring at the HAT logo but I can't find out where it's coming or what is trying to say, do you know the history behind? I'm curious to know.

Hey D i installed them Autotek's today and wow, they sound pretty damn good. The crossover still allows the higher frequencies on the 6.5's through to the tweeter. It's giving a pretty full sound . The Midbass probably isn't as impressive as SQ's or yours but it's good enough for me ! I crossed the mid's over at 120 Hz and they still put out a decent amount of thump !

Was there any special reason for setting the HP filter for your mid woofers at 120 Hz?

I could Easily set it to pick up the mids at 90 Hz but i liked the way it sounds. It's not a brick wall, it'll pick up stuff lower than 120 Hz. You have a diff suggestion ?

it sure depends on your taste.. most people would cross their mids at 60-80 hz (12 db/oct.)

[sqcomp]

In my case, I crossed my L8's at 40 Hz. I have a feeling that these L6SE's may be crossed in the 30's or even lower...

I have plenty of juice to push them, a neat pair of pods that make the L6SE's close to, I not completely, IB.

Mid bass is the key for me.

[_S7V7N_]

I may get an 8 inch sub to handle the midbass, but for now Imma let the 12's handle the 20 - 100 Hz Range.

[_S7V7N_]

I did some searching since you guys set yours different and this was what i found on Crutchfield : http://www.crutchfield.com/S-zucuJnc...overs_faq.html

In a hypothetical car audio system the audio frequencies might be directed as follows:

Low frequencies (say 100 Hz and lower) go to subwoofers.
Midbass speakers get frequencies between 100 and 250 Hz.
Midrange speakers would see frequencies between 250 and 3,000 Hz.
All frequencies above 3,000 are handled by the tweeters.

Keep in mind that the points listed here are not set in stone and do not apply to every car out there. The best crossover points for one vehicle might not be the best for another. It all depends on the speakers being used and the acoustic properties of the car. Most electronic crossovers allow you to choose from several crossover points.


Nothings ever set in stone, Like SQ has them kickass 6.5's and Derick does as well so there crossover points will be a hell of a lot lower than mine. The specs on mine say 60 Hz on the low end, I'd prolly do 60 Hz if i had them in an enclosure with the specified airspace i wouldn't worry to much about over powering them and possibly messing up my voice coils ( which is what i think happend to my component 6.5's ).

Here's something a little more solid to look at:

^ This is actually a good reference to have printed out and in front of you when tuning, especially with a 1/3 octave control...I speak from experience.

So D...

I may know someone at my shop with a 700.2. You might call Aaron at the shop and ask him about it.

Spurring you on a little more:


^A blurry closeup of the conceptual on the amp rack. I'm keeping it budgeted tightly. We went as wild as separating the two big amps, reversing them so you see guts. Then we'd place the four channel on a piece of plexi, "floating" and backlight that bad boy.

Instead we're going to show heat sinks on all the amps and have the four channel suspended above the two using a rack and a single piece of MDF that will be carved out on the insides a bit to show off the DD logos on the two big amps while still "floating" the 4 channel on the MDF piece. It'll be routered and painted to match the car. We still might do some lighting behind the 4 channel to show the big boys off.


^Guess what piece makes an appearance? :)


^ 48 dB slopes on all channels left and right, 1/3 octave control on all outputs, and TA down to .2 milis of control. Think about it D...






^I didn't finish tonight on these simply because I'm sending the grill inserts to be CnC'd...


^Rack construction? What rack construction? Pay no attention to the man behind the curtain! That's Jim...He's got a square face...

Do you think you will get good (level of at least F-3) 40 Hz in your kick panel pods? (Asking 'cause never had experience with kicks)

Also, why don't you open a separate thread dedicated to your project? Yours is interesting instal deserving a separate one ))

[_S7V7N_]

He had an awsome thread with lots of pics but deleted it cause people were being ______ . it would be great if that thread was reopened !

^ *meh* I hear you. I'm posting these pics to drive Derick on to do a little more...

Speaking of...

Derick, do you have an announcement about a certain new amplifier? :D

...Also, my grill inserts are being CnC'd this week. Nice! It'll be a brushed aluminum insert over an MDF ring. I'll be making two sets of rings, one for show and one for "go" (daily use).

40 Hz in a kick. Well, I'm attempting to recreate an infinite baffle loading on the speakers. What you haven't seen, right below in the sheet metal of the car we Yaris owners have plugs that go into sub frame...just by the kick panel area. That "venting" allows the speaker to load much differently than a sealed or even a traditional vented encolsure.

Having heard the L6SE before in a "tuned" vehicle (a 3x MECA world champ vehicle), one almost doesn't need a woofer...seriously...Dave had his Camry pushing his L6SE's down to 25 Hz. They had great attack and decay, great presence and the definite ability to play low. He had two 12" woofer IB loaded in the trunk. They only came alive around 30 Hz and below.

in my setup I have more power and much more control than even that championship vehicle I'm alluding to. This means good things!

Yeah! it was crazy but finally I got a NIB Image Dynamic 700.2

175 watts @ 4 ohms! for my L6s






I also got for my birthday an iPad! I know the P-99 it's iPod ready! I'm going to try tomorrow if works with the iPad
