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.

In my 96 911 993 Turbo l have a $8k system
and that still doesn't complete with that glorious sound of that flat six l'm also restoring a 1973 2002tii that's a bit of a resto mod and I'm tlhinking of installing the Pioneer head unit (single din)that has the flip out screen and will give me Bluetooth phone and Andriod Auto

In the tradition of my ancestors, always answer a question with a question....

I have a 2018 911 and it came with a Bose upgrade but who cares. When you get above 30 you can only hear the engine and wind which is what I like. Porsche offers a $6000 Burmester upgrade but unless you just drive around town it makes no difference. Perhaps on the Panamera it might or the new all electric.
