I can't answer for your 2023, but I can relate my experience with my 2021 Regular Cab (2 door) Silverado.
The truck (bought used with 5K miles) had the base radio and the sound was terrible, especially at higher volume. ...The distortion was unbearable.
I contemplated replacing the entire system and/or adding an amp, but started with the door speakers.
.....I installed Kenwood 3-way 6"x9" speakers from Crutchfield. (# KFC-6966S speakers & Crutchfield mounting adapters)
....They were all that was needed because the sound quality is GREAT. ...The factory radio has enough power that I can not be in the cab at full volume, and there is no distortion.
I also purchased Kenwood speakers (# KFC-X2C) to replace the dash speakers, only to find that there were none in the dash, but the wiring for them was present.
....Hooking the tweeters up, I found they overpowered the door speakers and there is no adjustment for fade or balance.
....I ended up locating one tweeter on the top center of the dash and the other centered under the rear window.
....I added two 4-ohm L-pads to allow adjustment of fade and balance of each tweeter.
While working on my truck, I had the truck windows and doors closed and the volume turned up. ....My wife came out to tell me she could hear it inside the house with the house doors and windows closed. ...I don't feel I need an amp or sub-woofers, either.
If I were to do it again, I would probably not bother with the separate tweeters as the 3-ways have them built in.
