OK I just improved my sound system further. I found some helpful ideas for those who are interested.

1) the factory sound processor set the bass and treble up. So to 'de-equalise' the factory tune, set the bass to -10 and Treble to -5.

2) build in amplifier is class D. So for it to work properly with other it need to have a 'dummy speaker load' before you feed it to another amplifier. You will find significant improvement in distortion.

Audison calls it universal speaker simulator: USS 4 | Audison - car audio processors, amplifiers and speakers

Audiocontrol calls it Load Generating Device: AC LGD's: Do your line converters put a resistor load on the speaker outputs of my factory amp? | AudioControl

Focal hi Lo V3 has a dummy load build-in. I used one for subwoofer channel and it works really well. Noticeable improvement. Focal HILO.V3 - Stereo Amplified Signal Converter. Note that V1 and V2 does not have that feature.

I also used cheap 10w27ohm ceramic resistors for the other 9 channels and it works just as well.

3) Digital signal processor (DSP) helps. I used a 4 channel Audison Bitten for the 4 mid-range and tweeter pairs. I tune it with an Andriod app call Audio Tools with a calibrated iMM-6 microphone from Dayton Audio.

This is my current upgraded setup.

This is the sound frequency sweep that I got from this with Bass set to -10 and Treble set to -5'

Hope that helps

Thanks for all the info. I am starting my SQ Comp build in my 2021 GT. Have you used the SPDIF at the factory amp? I am trying to find out if you still have volume control or if it is a fixed signal.
Also have you removed the plastic panel on the door to be able to deaden the door skin?

SPDIF should always be a fixed signal, otherwise you run into serious bit truncation

Yes it usually is. Just checking to see if anyone has actually used it. Some have mentioned it here but no real details about the outcome. I am planning to try it in my build but am not to the point to test it yet.

God I wish I understood all this stuff !

Would like my stock system to sound a bit better but have no idea.

Oh well, might start with removing the mesh stuff under the grilles.

Start with the really easy stuff.... what's your source? Use the best you can get. Also Dynamat in the hatch area improves the bass a fair bit

we will figure this out !!

Yes we will

I deadened all four of my doors, plus added MLV behind the door card.
It makes a substantial difference in the amount of noise coming in from adjacent cars. There was a bit of midbass improvement, but I was too lazy to take measurements.

I would definitely recommend it for the noise suppression alone.

What's my source ? I don't even know what that means..... lol.

I'm probably just going to start with some Dynamat ( as suggested ) and remove the try adjusting some factory settings and see where that gets me.

Did you have to remove the glass? Any tips or tricks to taking the inner door panel out?

Source, as in where are you getting your music from. (FM radio, Bluetooth from your phone, Music streaming service via carplay or android auto etc)
Start with the best quality source such as Tidal (music streaming service) via AA or CP, or hardwired. If you are using low quality MP3's you won't be getting the best source.
