2022 Toyota Prius. Doitor's g
After a long pause, its time to get back into the SQ game, so I decided to start a new build.
The main goal is to build a stealth system in my daily driver.
The car: 2022 Toyota Prius.
Source: Ill use two. First, the OEM head unit connected via high level into the DSP. Second, iPhone/Ipod touch into a Topping D10 DAC via coaxial digital into the DSP.
Speakers: IIAF Magnifica LE Carbon Fiber/Copper 3 way + 12" IIAF BL5 sub
Amps: Two IIAF D410 4 channel amplifiers. One for each side. Channel 1, 100 watts for the tweeter. Channel 2, 100 watts for the midrange. Channels 3 and 4 bridged to get 275 watts on the midbass. D135 Mono amplifier for the subwoofer (500 watts).
Processor: MINIDSP C-DSP 8X12 DL
Installer: Me.
Picked the car up from the dealer on June 22, 2022.

What do you do the first day you get a new car?
Take it apart, of course. LOL.
The top of the dash comes out in under 10 minutes, 5 if you hold my beer.

Also did a bit of measuring.
First, had to get the mic out and measure the OEM system.
Attachment 17787 Attachment 17786
Then used the osciloscope to measure clipping on the front and rear speakers.
With a 1 khz 0 dB tone, the fronts clip at 51/62 and the rears 53/62.
With a 1 khz -5 dB tone, the fronts clip at 56/62 and the rears dont clip.
With a 1 khz -10 dB tone, the fronts and rears dont clip.
With a 50 hz 0 dB tone, the fronts clip at 54/62 and the rears 61/62.
With a 50 hz -5 dB tone, the fronts and rears dont clip..
With a 50 hz -10 dB tone, the fronts and rears dont clip.

Re: 2022 Toyota Prius. Doito{rs g
Not a lot of progress this weekend.
Installed the USB extension in the center console.
The idea behind that is to keep the IPod in there. The right one goes into the Topping D10S, the left one is just 12v, so I hook up the Apple CCK3 into both and the Ipod into the CCK3.
Attachment 17949
Also added the "I dont trust you with my system switch", which cuts the remote wire.

First set of speakers are in. Woot, woot.
The original speakers mounted from the top. Had an idea to mount them from the bottom and make a "waveguide". Made a ring with 1/8" mdf and held it in place with wood tongue suppressors.

Used tape to make a mold.

Fiberglass body filler.

Regular body filler.

Made the baffle from 1/4" acrylic, used speaker gasket tape on both sides of the baffle and duct seal on both sides.
Attachment 17998
Added some deadener and hot glued everything that could rattle.

Covered with speaker grill cloth and into the car.

Yesterdays report.
Built a temporary 1.4 cubic foot sub box out of MDF.
Want to build a fiberglass box for the corner of the trunk, but my fiberglass skills need a lot of work and Im taking the car this weekend for a show.
Attachment 18130 Attachment 18131 Attachment 18132
Also ran my first Dirac tune last night and Im really liking the results.
There´s a learning curve for sure, but the quick tuning guide in this forum makes it a pretty straightforward job.

Re: 2022 Toyota Prius. Doitor's g
First DIRAC tune.
Followed the "Quick tuning guide" on DIYMA forum which made the process a lot easier.
Horizontal lines are 10db scale.
This is the tweeters graph.
Left=Purple
Right=Green.
Corrected response under yellow solid line.
Used a x-over at 1 khz pre-Dirac, but this tweeters can play pretty low.
Have them playing from 3 khz and up with 24 dB LR high pass.
Attachment 18140
This is the midrange graph.
Left=Yellow
Right=Blue
This speaker could play from 100 hz up to 6 khz in my install.
Corrected response under yellow solid line.
Have them playing from 320 up to 3 khz and up with 24 dB LR on both ends.
Attachment 18141
This is the mibass graph.
Left=Yellow/Orange
Right=Blue
This speaker could play from 60 hz up to 5 khz in my install.
Corrected response under yellow solid line.
Have them playing from 80 up to 320 hz and up with 24 dB LR on both ends.
Attachment 18142
This is the subwoofer graph.
This speaker could play from 16 hz up to 100 hz in my install.
Corrected response under purple solid line.
Have them playing from 80 with 24 dB LR low pass.
Attachment 18143
Gains and delay settings.
Attachment 18144
Im pretty impressed with the results you can get with the Mini DSP C8-12 DL and Dirac.
In 20-30 minutes it left the car sounding pretty good and it still has a lot of potential.

Took the car this weekend to the Monterrey Money Round event. 16 of the top cars in Mexico all vs all, no rules, 4 judges (including Richard Papasin and Ruperto Aguilar).
The top 6 places where pretty close.
1. 161.5
2. 161.125
3. 160.5
4. 160.125
5. 159.625
6. 159. Me. (Just got the corrected results).
Gave close to 50 demos with great feedback.
Now its time to let the speakers break in before the next tune and keep working.

Looking over the build thread, I missed to upload pics of two parts. Engine and kicks.
Here´s the engine bay using OEM looking wire loom, bolts and electrical tape.
Attachment 18165
The kicks where a bit more difficult mostly because of having to be in an awkward position.
After moving the wiring harness, theres enough room in there for a 6.5" driver.
Attachment 18166
Routed a couple of 3/4" rings.
Attachment 18167
Bolted and fiberglassed them in place.
Attachment 18168
Speaker in.

Cut a hole in the OEM plastic and riveted a speaker grill.

Santa came a bit early this year.
Been trying to get one from CSL for a couple of months with no luck and it seems they dont like to reply emails, so I ordered from Parts Express.
Will play with both the Umik-1 and Umik-2, keep one and sell the other one.

First measurements with the UMIK-2.
Measured the response of my midranges with and without a dash mat.
Showing the graph from 400 hz up to 20 kHz.
Mids are playing 320-3200, but you can see how the dash mat also attenuates the tweeter frequencies and the tweeters isn't covered.

Re: 2022 Toyota Prius. Doitor's g
Well, Santa keeps on giving.
This time its a CSL calibrated UMIK-1. (Umik-2 still not available).
Comparing the miniDSP calibration flie vs the CSL one, both are pretty similar up until 4 khz when it starts to get funky.
By 20 khz theres a 7.12 db difference.
I now have 3 microphones to play with. Umik-1 that came with the DSP, CSL Umik-1, Umik-2.
Ill take some measurements with all of them and share my findings.

Been playing with Justin and Ericas tuning companion Updated Justin tuning sheet ( Justin and Erica tuning... and used it to generate different target curves. Loaded them to Dirac 4 each time to the DSP and been auditioning. Its pretty sweet to hear the difference.
Made a graph to compare the curves.

Had a blast at Aggieland IX this weekend.
Some amazing cars and even more amazing people.
Had a chance to make a lot of new friends and hang out with some old ones.
Got to listen to several of the forum guys cars and a bunch of the top sq cars in the US.
Also managed to bring home 3 acrilic Texas maps.

Re: 2022 Toyota Prius. Doitor's g
It was nice finally meeting you. I wanted to demo your car, but never got down that way...in fact, I think I only demoed 5 cars all weekend. If they had given us timeframes for each org, I would have felt better walking around. Congratulations on the wins!

Re: 2022 Toyota Prius. Doitor's g
Nice meeting you too, Al.
And my cars doors are open to anyone, anytime.
I tend to make the same mistake and not demo a lot of cars, but not this time. Got to listen to all of my bucketlist ones and a bunch more and there wasnt a single one that dissapointed.
All cars have something cool or something that stands out and its not that often that you have access to that many sq cars in one place.
Like the free acoustic massage you get with your truck is a welcomed plus.

I watched all the videos about TuN/MAX on JL Audio´s Youtube channel and read the Smaart manual, so I had a bunch of theory but lacked the practice.
Asked a friend to loan my his MAX system this weekend and I spend a good 4 hours playing with it.
First I measured what Dirac did and then I started a preset from scratch following the guidelines that JL advices.
Learned a lot this weekend.

Re: 2022 Toyota Prius. Doitor's g
Decided to build a way to put the mics in the same spots and get consistent results.
Built one to get all the mics in the same plane (like MAX) and a second one for Dirac which asks you to for a cube around the central mic (first measurements).
So this is what I came up with.
This is the one for the MIN (LOL).
