Not sure how common sense of a question this is, but is the factory stereo in our car, or cars in general "time aligned" and tuned for the driver's position?

I've been doing my research on an audio system upgrade. Not an audiophile but music is a priority in this car as I'm looking for some more bass and quality. In my previous cars, I've done simple head unit/speaker/sub replacements with no attention to specs - unamplified speakers slapped together, basically. Have been blissfully happy thus far enjoying rattling loudness. This time around however, I'm looking to do things a little more legit. Planning to sound deaden doors and trunk, swap the head unit to a higher wattage one or add an amp to 2-way speakers. Had my eyes on the Sony XAV-AX5000 or 7000 when it comes out, but depending on responses I might have to look into something more intricate. A DSP seems out of my experience, although I was looking at the Kicker Key amp that has auto TA/EQ.

So in reading too much into time alignment and sound stage, where some swear by the importance of it and others say the average listener wouldn't notice, I was wondering if the stock stereo is time aligned so that I might have an idea if it's necessary for my tastes. I've never been in a car to play with such settings, and never thought any differently without it in previous cars (but maybe now that i'm aware). I tried sitting in the driver and passenger position to see if it was any different, may have noticed a difference but also wasn't sure if it was simply placebo or just that in the driver seat i'd be sitting much closer to the tweeters. Aside from that, any opinions/input would be appreciated. Thanks
