What do audiophiles do in their cars?

I specifically limited the style and brand of car based on the availability of certain sound systems.  I do not in any way think I can replicate the sound of my home system, but, wanted something pretty highly rated.  Most new cars, with integrated head units that control a myriad of things, are poor candidates for upgrades. 

I personally was not interested in anything Bose, so that ruled out certain models.  I also was only looking for a sedan (which are unfortunately slowly going away it seems).  Ford/Lincoln had the Revel systems and I was drawn to it, and ended up with a Lincoln with the Revel 14 speaker (maybe, I cannot recall exactly, there is a 14 and a 19 system) and have been quite pleased.  The DAC in the head unit is also quite nice it is a 24 bit DAC by STMicroelectonics (or something to that effect).  So when I play off my attached USB drive or via the iPhone connected via USB it comes through crystal clear.

My other car, the sports car (Mustang Convertible - 1983) has all Infinity and Kenwood components but I agree with prior posters, in that car it is more about the air in my face and the sound of the 5.0L V8 that is the music there.

I remember back in the day we used to put 12V to AC converters in our car to run a home stereo receiver, and then put some beat up pair of bookshelf speakers on the rear deck of the car to blast the music ha ha.

Wonder why they spend so much money and obsess over the sound when the music sounds so listenable in their car.

I have an m5 with the B&W sound system. Its actually decent. Better to go direct connect instead of airplay it sounds better. with that said, its fairly bright

Trying to accomplish a really decent sounding system in a limited space like the interior of a car is a mug's game. You can get close for a large amount of money, but why bother?

A car is something that you drive home to listen to your sound system. Having some nice background music is soothing and having it come out of a stock factory head unit is reassuring as you know you aren't going to come back to the parking lot you left it in to find the stereo pried out of the dash.

Besides, with the sort of cars I favour, the best sounds of all come out of the exhaust pipe - and I don't mean blatting flatulent V8s, I mean really good sounding straight 6 or V12s.  I don't even bother putting a radio in the older sports cars, it would interfere with the wind and exhaust noise!

 Hey,  need some advice. I have a 7 speaker sound system in my Acura. sounds horrible. I'm thinking of installing 6.5" Focals in 4 doors. Anyone have any experience with theses speakers? I've heard Focal Utopia's and was impressed.
