What do audiophiles do in their cars?

Stock Mercedes Benz Bose. 
Listen to FM NPR.  For me, Hawaii Public Radio.  HPR1 and HPR2. 
I installed a sd/memory card module in place of the cd deck.  I only use it in pockets around the island where there is no FM reception.
Sound system influenced car purchase?  No.

I don't feel my car audio will ever come close to my home systems. I'm not going try.  I will certainly not put music on while driving, relax, close my eyes, listen, concentrating deeply into said music as I do at home.  I try to drive with open eyes, attentive, concentrating operating my motor vehicle. Which  I consider a destructive killing machine.  Not my recliner that gets me to the grocery store and post office.

Hello,
I had a HK system in the Mercedes. That was very nice. I have a basic Ford now with the Sync 1 system. With Tidal Connect it sounds really good. No more commuting to work so I don’t need anything special. My wife’s Honda CRV touring has nine speakers. It sound really great with Tidal app. A good source really helps. 

Threads like this one are always used by some members to brag about the cars they own.

Surprised how many folks on here seem dismissive of car audio. Sure it’s not your all analog 2-channel where Miles David literally appears in your listening room, but cruising and bumping the toons is a blast. 
An X5 I drive sounded so so, but I upgraded with the full Bavsound package, all drivers, woofers, amp and DSP, and it’s all tailored to the vehicle without customization and it rocks. 
Way back in the day I had a Mazda sedan with 2 18” JL W3s, Memphis Audio amps, and MP3 player, and JL components and it was all soundproofed. I had to get a second car battery, and oh do I miss those days. 
Can’t imagine loving music and shunning car audio. Can’t imagine many things these days. 

My Lexus has a Mark Levinson system in it. Designed for the car, sounds great with classical or jazz.


But honestly, while the Lexus IS really quiet, it is still not the kind of quiet required for a true audiophile experience. So, you real;y have to wait to get home… or Bose QuietComfort on the plane.
