UHFS Speaker Upgrade in Premium Audio car

[Ironman Mark]

I see where many people have upgraded from door speakers in the standard radio, anyone have experience with replacing the front door speakers?
Same question for pilar and center speakers - keeping factory amps, is it a noticeable improvement in sound quality?
TIA

8" midbass in the door from the premium system will drop drop in place of the standard 6.5". As expected you'll get just a little more bass from them, but not a lot. Midrange might suffer if you run the 8" as part of a 2-way system without a midrange. The standard system has no way to drive the additional dash midranges; it is only a 6-channel system. Tweeters are the same between both cars.

For the Model propulsion 2022, what are the modifications compared to the 2021 model:
- Are the loudspeaker medium and the tweeter in the center of the dashboard removed?
- Are the door tweeters (at the level of the mirrors) and the loudspeakers mediums of the front door pillars still present and deactivated?
- Has the wiring plan for the connectors at the ECU changed?
- Something else ?
