Yaris Sedan Deadening and Sound system upgrade

[derickveliz2]

I'm glad I didn't sell my other woofers and amps,
so I can play/test and be creative with my install, I do learn a lot at the same time I'm having so much FUN!. Any suggestions are welcome!

It's nice to spend time with people we love! good for you, you are a good son! isn't your birthday this week?

Nice building the amp rack! What color LEDs lights are you going to use?

I'm using bright white LEDs. Notice the white paint on the inside of the rack? It's flat white. What'll happen is that when I pop the trunk, the LEDs will illuminate the rack and make the surround glow like crazy. The amps and trunk are dark...so that will further accentuate the contrast.

I got it from Jon Webb's G8 sub enclosure idea. Im going to see Jon at CES again this year. I'm glad to be able to consider him a friend. He was awarded Installer of the year in 2011...it turns out that another friend of mine, Jeremy Carlson received the 2012 Installer of the year award at MERA Knowledgefest this last weekend. JC is the one that gave me "magic juice" on my Bit One recently. Gotta love connections...

That is going to look AWESOME!

Well after 600+ miles with the IDQ12 in the rear seat and some adjustments it can work pretty good! I know it's not a fare comparison but due to the power I'm using, location and enclosure types! if I had to give numbers would be like this:

IDQ12 = 10/10
i6SW = 9/10

Yes the extra little boost on bass that the IDQ12 provides is very little (about 3db or 10% more bass boost), Now I can boost the i6SW alone and perform the same way or even better than the IDQ12, with the exception of Super Loud music. The i6SW doesn't like to blow your ears and nose like the IDQ12 but I'm not that kind of guy any more. If I could get the IDQ12 up front would be another story. but I can't. And the i6SW is working AWESOME in the BASS department, That is way I'm going to try 2 of these babies!

I really like my music to feel the BASS from down all the way up in a BOLD way; what I mean is I like to feel the BASS even when the volume is low, Moderate, and High (not Super High).

I heard many systems that at low and moderate volume there is not a good BASS, you have to crank it up to feel the BASS, I'm naive here but maybe Sqcomp could tells us a little bit more about how is this issue treated in competitions.

Taking in mind that if I increase the gain on the IDQ12 Sound Quality goes away and SPL is Welcome, but the BASS starts coming from the back... and...

There is nothing more Natural that feeling all the BASS coming at you from the Stage!

The IDQ12 is out of the Yaris, I was getting a winding noise (very little but annoying to me) I guess all the extra RCAs running around were picking up that noise.

A second i6SW in Yaris...

After taking out the IDQ12 today, I was playing Hotel California, Honestly....

What a virtual experience, I feel good when I don't have to adjust the BASS for each song! every thing just plays AWESOME! no matter what kind of music, just hit it!

The i6SW hits my chest in a way I just can't describe. I know 2 doesn't means Double but since I'm getting this second woofer for FREE, it's worth the effort!

I was about to say...that extra space in there is going bye-bye with a second woofer up front.

Would you be ditching the foam and the inserts under the carpet for a little more space?

I'm working on a center console idea after INAC next month.

In competition, there is a category of judging for linearity at the sub bass level. This is where we get detailed and picky. You could have GREAT sound at a low to moderate level but let's say your amplifier and sub don't mesh well because of power issues at high linearity...well, you get kicked down a couple points for it.

There's also the category of imaging, ambiance, and tonality. All are affected by the sub woofer at some level. It all blends really. If your bass is too overpowering, much like the dual DD1508 setup I messed with earlier this year, you get knocked down for it. That instance had a peaky enclosure with STOOOPID amounts of bass. I took the level down 12 dB at the source to try and tame the amplitude of the signal. I replaced that setup with the ID8 then dual ID8s. I don't know why I even considered a vented DD option (aside from flipping the bird to the SQ world for the hell of it).

There is one reason I'm not using a Hybrid Imagine woofer yet...actually two. One, I get better response from the sealed enclosure woofers and there's a Legatia 13 coming out in a few months that I get to play with.

No, I'm not going to remove anything under the carpet, MLV layer is above and rather keep the road noise away, and since it's only an experiment why bother now. If I really need the extra space I will, for sure.

Center console idea? interesting? but I can imagine it's going to be hard to accomplish. Expand please.

Thanks for the info about linearity at the sub bass level, I love to be picky in that department.

I know about the Legatia 13 coming soon, for now I get to play with 2-i6SWs I went to the post office today and there she was!

Just to expand more on this...

If every thing works in a positive way... I'm not only going to take out the inserts and foam... I'm thinking about cutting the metal floor and lowering it about 2 inches, then I can build a dual box for 2 i6SW's and rise the floor 1.5 inches.

Letting the vents breath the same way facing forward towards the center of the fire wall.

Just another crazy idea so I don't call this Build "Done!"

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!

[sqcomp]

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.
