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.

I use the stock system in my VW GLI and stream Qobuz or the Relisten app from my phone.
CD's in a fair system for 2008. Fosgate? Except the subwoofer under the driver seat. Useless except for gluteus massage. I turn the bass control down to zero. Sometimes I run a Patch cord direct to my V40 phone for Tidal. It has an above average Dac.
Stream Tidal over my android phone on my 2020 Lexus ES350 UL with the factory Mark Levinson stereo. Sounds pretty good for a factory stereo but the car is very quiet.
Pulled the stock Ford stereo out of the truck, put in a Sony WX900 & a pair of Rockford Fosgates. Stream Qobuz high rez. Sounds very nice.  
Pioneer head unit that runs Android Auto that I can stream Tidal, or downloaded hi-res from the Tidal app if I lose cell service (I live in Alaska), as well as flac from a USB drive.
Morel Elate Carbon 3 way component set up front, and in back as well.
Custom A Pillar Pods for mid and tweeter. 
2 JL Audio 10W3v2 subs in a JL Audio Stealth Box.
3 JL Audio Class A/B amps.
JL Audio DSP w/ Time alignment and Parametric EQ for every channel. Fully sound wrapped in DynoMat (roof, floor, all 4 doors).
Upgraded Alternator, and dual battery under the hood.
Its amazing. I have had similar systems in every vehicle I have ever owned. The system is tuned to be punchy but very transparent. I’m not into the high SPL "boom" that bugs the guy next to you at the stop light. Having a system like this in my vehicles was also a "gateway drug" for my kids to get into hifi as well because they were listening to good sounding systems at home, and in the truck their entire lives.
Having a system like this was also essential, as I am a working musician and will learn songs while driving, and the stock systems in every vehicle I have every owned just wouldn’t cut it when you’re trying to isolate a single instrument in the mix.....
That being said, the best stock system I have ever had was the Bose system that I tore out of the GMC pickup I drive now :-)
