I've got this '02 9-3 that basically has no functioning stereo components. Blown front & rear speakers, dead door amp, dead CD player, dead CD changer. Dead dead dead!
A few weeks ago I pulled out the blown 6x9s and installed some Pioneers. As others have noted, most 6x9s don't fit in the stock location in the stock way - the speaker baskets tend to be larger than the opening. I used a carbide burr on an air grinder to basically remove the lip from the metal mounts. Of that I did not get a picture, but no more interference. Pioneer 6x9s were $60 for the pair.
Next challenge was replacing the door speakers. There's all sorts of information about what's usually in there, but in my experience (numerous T7 OG9-3s), it's always a 4ohm 6.5" speaker. A variety of speakers will fit in this spot, but many require modifying the plastic baskets. I didn't want to do that. I went for Rockford Fosgate R165S, which is a 2-piece component set at another whopping $60. The R165S is really a 6" speaker, so a bit smaller than the factory speaker... and it fits with zero modification:

I will use only the woofer - the tweeter is scrap!
(Interesting note: The R165S is listed as a 4ohm speaker, but measuring across the terminals yields 3ohm. I realize this is not a true measurement of speaker impedance, but it's something quantifiable
)
Hey, an interesting note... Speaker terminals are two difference sizes (positive and negative) and neither are common .250" terminals. I used this for the rear and door speakers:
https://www.amazon.com/gp/product/B07DS7ZC5Y/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1
This kit includes the correct .187" and .110" terminals as well as insulating sleeves. They fit and look nice! $10 for all the terminals you'll ever need.
A note: On the rear speakers and door speakers, the #2 terminal is the positive, the #1 is the negative... as indicated on the black factory connector.
The next challenge is repurposing a Pioneer double DIN stereo I've had in the garage for a year. It was not expensive new, and it's worth about nothing now, so it's going in the car.
I've never gone for a double DIN in an old 9-3 because I hate the idea of cutting the dash and I kinda wanna save the cupholder, but in this case budget first and what's in the garage is $0, so here we go...
This is what I know so far:

We'll see how things go!
