What do audiophiles do in their cars?

"Tweeks" (long explanation) and sound deadening has made the factory installed stereos in my late model cars much more listenable.
I don't have stereos in my old/vintage vehicles:
a) can't hear them anyway via wind/road/motor noise
b) want to be able to hear when parts from a 50+ year-old-car fail or fall off the car completely

Have very good system in my Lexus. Did not renew xm satellite subscription after trial it made my ears bleed with listening fatigue. Have plenty of good local radio stations both music snd sports talk. Some bluetooth apps can sound ok but some like pandora are as bright as the sun. I do have an aux plug i can us and have thought of trying out a dragonfly from my iphone. Will update if i do.

For many years I owned a Volvo sports with a Dynaudio stereo. I played it in the showroom when I bought the car, and never again. I never listen to music in the car, I never have music on in the house. I never have background music on anywhere.  I have a dedicated music room where I listen and apart from rare trips to dealers or other like minded friends houses, it is the only place I listen to music. Anywhere else is just noise.

Hello bigtex22. I installed the best Focal car speakers (wood fiber cones, $500 ish) in my Mazda van and it made a great improvement. A bit pricy, I was flush at the moment, but worth it in the long run.

Your music room isn't in your house?
