Honestly, as long as it’s easily DIY upgradable (accessible speaker mounting locations, standard DIN panels, etc) I am all for this. Most OEM audio systems are stupidly overpriced and suck complete donkey balls compared to what you can get for a few hundred bucks at Crutchfield and install in an afternoon.

For the last 20 years or so, most factory audio systems are so integrated into the rest of the electronics that they can be an absolute nightmare to upgrade unless you are a pro–which means you get the worst of both worlds.
