Yaris Sedan Deadening and Sound system upgrade

[sqcomp]

Sorry bro...I was up in Canada this last weekend winning! Apparently, IASCA has me as the best sounding vehicle in the Pacific Northwest region in my class. I won a 1st place showing with a score of 225 in SQc Amateur division. It was a regional championship event, the Western Canadian Finals. It was a 3x registered event for IASCA. This means that I can compete at SBN in Daytona Beach Florida with the car and go for a World Championship.

...Alas, I don't have the time or the money to take my car all the way across the country and back for a two day event...

I can still take solice that without proving any more, I have the best sounding Amateur class vehicle in the region this year.

Congratulations!!!, I can see (feel) how you end up in 1st place, I'm very happy for you.

Now you know why I don't compete! it's just too much of a commute for me, jeje LOL

Now, to you Derick.

Why don't you simply glass the floor? You've got everything taped...

Also to those who don't understand about the aiming of the woofer, as with mine:



The sound is omnidirectional. That being said, there is a feeling difference between a standard forward or up-firing woofer and one that is downfiring. I feel my bass a LOT lower...pretty much from the bottom of the seat and through the body of the car.

The MLV IMHO should be applied to the inside of the enclosure once it's formed.

Also, D...I'm thinking that our resonant frequency is at 42 Hz. See if you can find a 42 Hz tone and run it through. You now combine that frequency and combine it with the tuning frequency for your enclosure of, oh let's say 38 Hz. Then that extends the response of the enclosure to fit your vehicle's response more accurately.

Yeah! I'm still in "thinking" mode, you know how designers work, think think think, then get it done. (sort of).

Yes, 38 Hz it's my target according to the enclosure Design Criteria...

I realize what your saying about bass being omni directional, that makes sense. What I was thinking of was the amount of volume from a smaller speaker hes using. Course I also realize the enclosure it's in will affect it just as much. But you feel the sound from the back of the speaker will do as well as what comes out front? Thinking of it going into carpet vs what enclosure under your trunk mounted set up.

2 different enclosures,

Sqcomp has a sealed enclosure with the woofer upsidedown, yes the back of the woofer is what creates the bass, it doesn't matter.

I'm doing a ported box (vented) and yes the back of the woofer is what produces the bass, but with a little help from the port, bass increases a little more and bass goes out through the vented port that will be facing towards the fire wall.

Here are a couple of diagrams with different types of enclosures:

@ sick,

I do get what you're saying. What I wouldn't do would be to put both the woofer AND the port facing down. I'd actually aim the port up into the dash or at the firewall.

@ Derick,

Keep your pillars the way they are now. Let me do the R&D. If I get an improvement with the left side width, I'll let you know what I did so IF you want, you can do the same type of thing. I'm looking at making waveguide-type panels for my tweeters right now as well as moving the mids deeper towards the windsheild.

The closest IASCA competition for you would probably be in South Carolina or up in Canada (this weekend). I ultimately think that you should give it a try at least once. Let me know if you ever decide to take a weekend and go to one, most likely I'll know one of the Team Hybrids guys there so they can take you under their wing.

Ok, do your R&D I'll wait (O:

I would love to have my set up go through IASCA's judges, I'm very curious to see where I'm!

And why? I want the subwoofer in front....???

This is why: when I have my IDQ12 in the trunk, my seat vibrates! and at very low notes, it can be localized! (in the rear of course)

When I have my IDQ12 in front, my chest feels the bass, like it's coming from the Mids! payless sensation! x 1,000,000

You should feel the power I have with this S2b amplifier. I've got the sub dialed back 11 dB and it's plenty loud. Take it down to 5 dB down and OMGawd! The mirror actually shakes so hard it moves out of joint. I actually get "rattles" from the back bumper. They're more af a very subdued movement of the entire trunk and bumper...

I just had the balls to try that today.

D! Download a glitch song from Vibe Quad called, Funkwear. That is a bad ass track. Get it and get back to me after you hear it in the car.

Speaking of localization on the rear sub, what's your crossover point and slope on that?

I you could transform your amp power into Horse Power, your Yaris should be able to do 0 to 60 mph in less than 5 seconds!

OK, I have the song I'll try it tomorrow!

Actually, I have a little project in the works that deals with a stripped down 1987 Honda CRX, a brand new Ohlins race suspension, a Hartley H1 engine, and a sequential gearbox...

CRX my favorite car since I was 15 years old!

I'll check it out, give me a few minutes...

It's 63Hz at 12 dB/oct according to the software of the P99's Auto T/A and EQ

Sounds AWESOME!

The Sub "shows off" I really like the IDQ12

Lows, slamming hard really nice, but at really high volume my left door (plastic panel vibrates and rattles)

This track has a very nice center image even without a singer!

The stage width goes from outside sail panel left to right, very interesting "wuogle" sound


Should I be looking for something else?

you have the L6's in? If so, take the crossover point down to 45 hz at 36 dB and the L6's to 45 at 24 dB. The TA on the sub (if it's in the rear) should be about 60-ish inches.

Imagine that little CRX (which weighs 1700-ish lbs curb weight) stripped down with a racing suspension on it...add 500 N/A horsepower at 10K RPM WITH a sequential...you get a little car that has more power to weight than a Saleen S7 Twin Turbo. I'll betcha I can get that car down to mid 1400 lbs. That would put the HP to weight of the car (if set up correctly) greater than a Pagani Zonda...

No I don't have the L6's in, I'm sure that is why the software is going that high!

But I'm saving this info once the time comes by! even though the way it sounds (Mid/bass) now was amazing for the DIYMeet members at the Massachusetts meet and had a chance to hear my set up, one of them had L6's and he was very much impressed,...

so... I guess it just gets better and better!
