What do audiophiles do in their cars?

Have Mark Levinson system and 8 track as well.

In the car I listen to the iPod. In the 911 I drive.

I listen to sirius xm, which has poor sound quality. My oem stereo is not good and neither is the road noise. The setbacks of upgrading the stereo like removing panels is not worth it to me. The other problem is integrating a better stereo with the stock "infotainment" systems. In the heyday of car audio there were only like three options for a really good head unit. I would be surprised if that kind of sound is available today, but I do not know for sure. 

Who cares?
Yes the stock stereo sound and features have some bearing on the purchase. Both of my cars sound good enough with the top line trim.
I had a ’95 Ford that benefitted immensely from changing out the door speakers. Those days are long gone.
In a moving vehicle you will get far more SQ improvement from
sound deadener

instead of better playback equip.
If you wanna blow dough go Crutchfield.

I listen to inde radio for musical discovery. In Austin, I'm luckier than most for this option with 3 great stations, one totally local music. 

Keep the roof open, and let the warmth of the sun reduce fatigue from tinny treble. Cheers,
