What do audiophiles do in their cars?

Standard CD system in my Lexus. Nothing great, better than nothing.

The  Mark Levinson in my Lexus LS is adequate. 

If you want to hear the good sound in your car , first it neeed to be luxury like Lexus LS sedan or mecerdez s class they are well insulated from inside dead quet and you can enjoy mark levinson in Lexus or high quality brand audio in mecerdez Benz , that what they designed for !

What do audiophiles do in their cars?

While I'm driving or parked?

If it's when I'm parked, I'm not saying!

XM Radio with whatever the best "optional radio with *** speakers is available. I think the Pacifica has Harmon Kardon 20 speakers and a sub, and my Corvettes always had a Bose system. And I must have the "optional biggest wheels and tires on whatever I buy. My wife has grown to accept that I will absolutely not buy a car without a Sunroof, great radio and nice wheels and tire package.. Always runs the price up on my automobiles, but why make payments on something I don’t want ..
