Got your mind working again?

I hear that! I'll shoot some pics soon of more work on my trunk.

As always!

I posted the drawing above on DIYMA and some claim I'm going to have phase issues because of the woofers aiming in different directions!

so I did this other sketch but what do you think about that?

This is where the old fashioned idea of building a test enclosure so you can move things around and put the speakers in different places becomes really smart.

I did that with all my different subs in this car...especially after that phasing nightmare of placing the 15" in the rear right corner of the trunk and having at least a 3dB loss in out put no matter what I did with the phase. I think I doubled up on acoustic phase demons with that placement attempt.

I'd build a test enclosure shape pretty much as you have it in the picture. One question though, tell us about the ports and their locations. Why to the rear?

I agree, nothing better than trail & error for me.

Ports are aiming towards the firewall (like the one I have now), what you see as black ovals represent the i6SWs, not ports.

I've got to get you pics of the trunk. I just got slow tonight. I need to sling the gaps on the left side of the trunk. That'll take a few days to complete given my work schedule. The I get to play with the right side. That's a little more work since I made an exact shell of the OEM trunk lining. I've got to place the fiberglass panel in on the shell and then cut the extra glass on the form out from the back.

Then it's trimming and filling...then carpet. I've got to get this trunk done before the 17th...

[derickveliz2]

That looks like a lot of work!

I keep changing the pics :)

Tomorrow evening both sides should look similar. It's interesting to me that the Yaris trunk set is a little off center. This was my first time attmepting this...you can tell.

With that being said, I see a lot of improvement on this in the future. I'd look for the Bit One to be placed on the left side soon. Of course I'm going to clean up that back board. The wiring is pissing me off with it going all over the place. Yuck! I'll move the tank up and left a little. The board will be carpeted and installed correctly. The other side holds the fusing...

More pics are about to come down in the next 24-48.

I leave you two alone for a couple of years, and THIS is what happens.

Nice to see you around AM

[sqcomp]

AM! WTH?

Where have you been?

Dood...I'm taking a Yaris to IASCA world SQ championships...That's worth two years isn't it?

[Alien Mantis]

I must say, you guys have really been doing some amazing stuff.
I had to catch up on this whole thread, took me awhile to read it all.

I see you have been working on so many of the finer details.
I was surprised to see Derick was running those small sub drivers. ( Those i6SW )
I thought is was also interesting to see you guys playing around with tweeter mounting angles in the A pillars and bouncing it off the windsheild. I was never a fan of aiming tweeters at the listener. I'm a fan of off-axis tweets. Tweets can be harsh anyway, why aim them at your face!

SQ: you are definately pro-level. Gratz on your work so far. I see about 4 or 5 of you guys on here that really take it to the next level. That's your "thing". I respect that.
You know me, I appreciate hi quality audio but never saw the sense in spending alot of money on a really high end car audio system, but if that's your hobby, nothing wrong with it.
After I did that modest system in my Yaris, I have been listening to it and living with it since you last seen me on here. I am about to make a few changes to it. It has been great, and I have been enjoying it, but it has a few minor issues that have been bugging me, and I will try to address them.
I am on step 3 and you guys are on step 1,249.

You guys put so much work into your systems. I see you are still fans of the HAT stuff.

SQ is going to laugh at me: one of the changes I am going to make to my system is I am ready to ditch that TypeR 10" sub in the slot-ported box. For my type of music, it just doesn't nail it. If I listened to rap, jazz, techno, hip-hop, or country... it would be okay. But it isn't really cut out to play the tight fast beats of power/prog metal.
As SQ once said, the TypeR is an SPL pig. I never forgot that. And you were right. I still say the TypeR is a great sub. I'm sure my box is more to blame than the sub itself. I could put a pair of TypeR tens in a sealed box and be happy with them. But they take alot of AMP to push them. They are power hungry, especially the new ones.
My other issue is ROAD NOISE. My Yaris is just too noisy. So I am going to try and do some sound deadening. Nothing fancy, just something that will help a little bit.
I know you guys are experts on this subject, so feel free to offer a suggestion or two. I would appreciate it.

Keep up the good work guys. I came back here just to see if you guys had actually FINISHED your cars, but as expected, you are still tweaking away on them! Always something else to do. Always a new trick, or a new piece of hardware huh.

SO, since I left, what has been the biggest challenge with your systems?
What is your favorite amps now? How much farther do you need to take your system to get them to where you want them to be?
Derick, what is YOUR goal? Are you going to compete with your Yaris?

[Alien Mantis]

I'm not a fan of that sub box on the front passenger floor.

I know exactly what you are trying to do, but that is a huge compromise.

You know how most people do it, they just overpower you with BASS so you can't really tell what direction it's coming from.
You guys are so focused on creating the perfect "sound stage".
In a large open room, it's pretty straightforward. In a car... it's a whole different story.
I wouldn't even want to try and tackle it.
But I guess that's the whole challenge of car audio SQ competition, isn't it.

Thanks AM,

Challenge... Learning, Listening, Tuning, Understanding, Time, Money and Tools!

Favorite amp?... My old Premier (Pioneer) amp 400 watts RMS directly into my 6.5" woofer it's amazing,

but The Gold is for the Image Dynamics for the Mid-Bass (HAT L6's) at 175 watts x 2, in some songs I turn off the Sub just to show off, almost no change in the music, and people go AAAGGGHHHHH

How much further?... If I had the time and money mmm you wouldn't believe it! but reality... I would like to finish every detail, to make everything look neat!

Goals? my goals are all left behind, the more I learn and the more I'm getting from my system new Goals start to show up, It's like the never ending story.

Compete? ... you know I have many invitations, (PA, Canada, Main, etc) I would love to go, not just for competing and see where I'm, but to learn from others.

All my SQ local friends have a big respect for the little Yaris, and they look for my advice, that makes me feel good too.

Ironically the Yaris turned into a very good platform for my system, some times I dream "if I could buy any car to install a SQ system and improve what I have now!" .... I get good PLDs (9-inches) with my Mids, Tweeters are far way from me, off-axis, left tweeter is 48" away from my left ear, The Sub up front fits perfectly and I can still have a passenger, and the Lows (Mid-Bass) in the doors work ok, would like to have them further up but like you said, in a car everything it's a challenge.

I love my yaris, honestly drives so good, looks good and sounds good, I would be heart broken if I had to let it go for other car.


I'm not a fan of that sub box on the front passenger floor.
The single i6SW is not on all the floor is took to the center console leaving enough space for passenger, the 2nd i6SW is just an experiment, but I'm very pleased with only one i6SW, lately I've been playing with other woofers, and even the IDQ12 in 1cf sealed box! against the i6SW and at the end of the day, I just go back to the i6SW... Sound Quality and overall performance, any music... just throw at it and without any adjustments the system will play it beautiful. Off course this is not a SPL system so don't expect to blow your ears! or to be one of the guys that you can tell his coming blocks away!

I know exactly what you are trying to do, but that is a huge compromise.
Please expand... to me it's all about a natural sound-stage

You know how most people do it, they just overpower you with BASS so you can't really tell what direction it's coming from.
I know! As far as of today all systems I've heard like that hurt my ears and take away the beautiful letters "SQ" from my equation and no matter what... I still can tell where it's coming from "The Back"

You guys are so focused on creating the perfect "sound stage".
YES! YES! YES!

In a large open room, it's pretty straightforward. In a car... it's a whole different story.
Agree 110%

I wouldn't even want to try and tackle it.

But I guess that's the whole challenge of car audio SQ competition, isn't it.
YES! but in my case not for competition, just for pure satisfaction and joy!
When I listen to my system I forget about commuting, problems, traffic, mortgage, Milk, meetings, news, etc, etc.

Welcome back! AM and don't forget about a layer of MLV to block the road noise. Now you can buy at H.D. online at a good price!

AM - I completely understand wanting to keep the agenda simple in the car. In some ways I do to... *can I lie through my teeth in the internet?*

A lot of money is relative. I know Scott has something near $300k into Black Betty...

I completely understand about the Type R. Try a small sealed enclosure 10" that's sensitive if you don't have a lot of juice to push it. Heck, I should give you my dual 8"s to try out. I LOVE them with rock. Rage's Take the Power Back is specfriggintacular in my car.

My new piece is going to be a whole new center console that'll integrate the subs in the back and separate the rear floor with the two downfiring subs.

Biggest challenge with MY system? Being content. Figuring out how to do all these tricks that you don't see. Learning new techniques to do new things.

Favorite amps? That's a trick question. I have the three DD amplifiers that I'm currently using in competition. I've chosen those over a McIntosh 6 channel I have sitting in my garage right now. Why? More dynamic power. Do I need it? yes and no. One never knows when you're going to need an ALMS Corvette C6R on the freeway do you? :)

The amplifiers are fine just the way they are. I'm playing with trim and making the car pretty and different. It should please all the Yaris owners to know that I'll probably be the only Yaris at IASCA SQ world championships on the 22nd. :)



I'm getting there...I have two weeks to install the amps, LEDs for the amp rack there, install the solid state relay and tune my car with that Bit One that has "magic juice" in it...

[Alien Mantis]

$300k ??? I didn't even think that was possible.

Dual 8's would be good for my kind of music.
I am definately going sealed box this time around. I have 400w RMS to work with for just the subs. ( Unless I want to buy a bigger amp, which I would rather not. ) It should be enough power to get the job done if I pick some efficient drivers and go with the correct box. As I said, my system has been fine. I've been enjoying it. I just decided to tweak it a little bit, and try to get some sound deadening going. Chassis is noisy.
If I can tighten up the bass a little, and control the noise a little, i'll be totally happy.
You know how it is, you can't leave it alone forever. ( Even me! )

Is that your trunk? What is the air system for?
You might be the only Yaris at the competition because the Yaris is probably not the best starting platform to work with.

When you said $300k for the black betty, is that the whole car, or just the audio system in it?
Any links to some pics of the black betty? I wanna check it out.

Here's an introduction to Black Betty. When Scott was shooting this, I was up in the suite cooking for his clients. Later that day when they shut down the convention hall Scott was dealing with clients and asked me to shut down the car. THAT was very interesting. I spent a little time listening...

400 Watts is fine mang. Just get a woofer or two that are efficient and into that sealed enclosure. You'll be amazed what the "feeling" is when you have woofers that combine well with your mids (and with the music as a whole).

What's in my trunk is three amplifiers, a compressor and the air tank. What's the tank for?

Oh... i understand now. That is one sick car. I really enjoyed the engine compartment. That is a show winner for sure.

That's the plan. My current sub does not seem to "combine well" with my mids. My current system seems to be optimized for RAP music. It does that really well. My ported box is tuned for that stuff. I need it to be more optimized for METAL. I'm going with two Infinity Reference 1060w subs this time, in a 1.5cf sealed box. These subs are effecient ( 91db ) low power ( max RMS 275w ) and have a factory rated Xmax of 13mm. On paper, they move some air with lower power requirements. Going from a single sub to 2 should keep my SPL up, while the sealed box will tighten up my response. Very basic stuff compared to what everyone else is doing, but that's where I am at. Got six 12x24 sound dampening sheets coming too. Probably need to buy some more because I plan to do the rear hatch area as well as the doors and rear quarters. So much road noise in this little car.

Ah, okay. I didn't know if you had air-bag suspension or something.
