    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.

    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.

    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.
