What do audiophiles do in their cars?


All of you forum members with your killer home systems…what do you listen to in your cars?  Do y’all have custom stereo systems?  Does the quality of the stereo system actually impact your car buying decision?  I have a B&O setup in my 2021 truck, which was an upgrade and sounds decent enough, but nothing compared to a typical HiFi home system.

The furthest dip I will take from my main system is my headphone office system. Once interested in a car system, I now will not listen to music in the car. On Serius/XM in the car I listen to cable news.
These days there is so much inter connectivity with the whole “smart” system that runs through the stereo seems it’s not like it used to be where you could just rip out the head unit and put an aftermarket in without losing a lot of functionality. 
The Bose system in our Escalade actually sounds pretty damn descent. Especially on 5.1 dvds. 
I listen to a 64GB usb stick with low rez copies of my cd collection, and FM.

Good enough on my premium stock Subaru Outback system.
