    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: Italia HiFi BL4 Carbon Fiber/Copper 3 way + 12 inch sub

    Amps: Two Italia HIFI 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.

    Removed the hub caps and got some wheel center caps.

    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.

    lso did a bit of measuring.
    First, had to get the mic out and measure the OEM system.

    27.jpg

    28.jpg

    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.

    This is awesome. I opened my car up the first year I bought it as well to install a new head unit, behind head unit amp, and new speakers and it was night and day. Thanks for sharing.

    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.
    Center Console 6.jpg
    Also added the "I dont trust you with my system switch", which cuts the remote wire so the dsp and amps wont turn on.

    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.
    IMG_1068.jpeg
    Used tape to make a mold.
    IMG_1070.jpeg
    Fiberglass body filler.
    IMG_1071.jpeg
    Regular boy filler.
    IMG_1080.jpeg
    Covered them with black felt.
    IMG_1207.jpeg
    Speaker mounted.
    IMG_1215.jpeg
    Made the baffle from 1/4" acrylic, used speaker gasket tape on both sides of the baffle and duct seal on both sides.
    IMG_1222.jpeg
    Added some deadener and hot glued everything that could rattle.
    IMG_1224.jpeg
    Covered with speaker grill cloth and into the car.

    Your braver than I am
    My stereo guy said he could cut and splice wires, and guaranteed me he could make my DSP work "without" a factory harness ...
    But, he told me what I already knew, that if there were any electrical problems > even if < they were not caused by the stereo installation, Toyota would totally bring that up, and use it as an excuse "not" to honor my factory warranty ☹️
    If my car were out of warranty, I'd totally trust my install guy, but just can't risk losing my factory warranty.
    I sure would love to hear your system though ! As nice as mine sounded in my 2019, I'm sure this is nicer ! And that would say a lot !
