What do audiophiles do in their cars?

It depends.....

In the Focus, whatever amuses....but I don't expect 'perfection'.
In the Land Cruiser, less....but I'm preoccupied hustling a not-so-nimble overweight beast.

Driving the Dodge dually, towing a 20' trailer with a Bobcat and a couple of it's attachments....
I'm working on not letting you kill us both by doing some bone-headed maneuver in front of me.

I can stop on a dime.  If you're not paying attention to what's going on around you, it may be in your pocket.

Save your musical excursions for home, where you're not doing 70+ in some NASCAR fantasy 'midst the rest of us.

I grew up with LA freeways....All of them.

I read the memo...and bailed in '75.
Spent the intervening years driving in a lot of cities, superslabs, spaghetti intersects....

Speed itself is 'fun', but outright Stealth is more entertaining, btw...;)

Rubber side down, y'all....J

Short list....Vdub, Benz outta $, Owdi'....

Beemer Taxi?!  Sacrilege...omgawd....

POORchu!!!  Say no....9,9, nien.....

I have 3 vehicles and except for my Golf GTI which has a very nice stereo system i have upgraded the other 2 with Bluetooth players and decent but not extravagant speaker setups.  I predominately use Tidal playlists i have made up though on some of my longer trips 2500+km reception is not available, so I am sometimes reliant on saved MP3's on my phone, I carry around 50Gb of music for those times.  My ex Australian Army 4wd (Perentie Commander) is generally towing my semi off road van, so it works hard, so I have sound proofed it somewhat, floors and firewalls with double sheets of Roadkill, has a big turboed Isuzu truck engine under the bonnet which makes some serious noise so I have the speakers mounted in a false roof to blast away just behind my head or use noise cancelling headphones which cannot be used going thru towns and cities !!!  I need music to survive when driving long distances.

In my next car I want a better than stock hifi system, I don't understand why people don't order it everytime they buy a car.

So yes, my decision is influenced by this, I wouldn't buy one next time with basic sound system.

So, the correct answer is, "Whatever they want."

Sorry, you asked.

In my C-2, which is a DRIVER that I decided to buy after years of trailer-queens and a room full of dusty trophies, I put in a system against all the "rules."  The C-2 world is composed mostly of people who "listen" to their cars, and I get it.  I do too, sometimes. 

However, on a longer drive, I like some tunes, so I bought, before the major price increase, a look-alike radio from Antique Automobile Radio in Tampa (really Palm Harbor, but close enough for people who do not know the state.) Current price is $700; I got it for less a few years ago, and it is the same unit. 

Then, I was able to modify the Custom Auto Sound footwell speaker enclosures to fit my car, which has factory A/C (pretty rare--only 5% had it).  So, when my daughter is with me, she can blue tooth her music through the system, and I have a plan to do something along those lines as well.  

The daily driver (2007) needs a new radio--all of a sudden it is static-y when the engine is on.  I don't know what I will do there yet.

Cheers!
