What do audiophiles listen in their cars?

Snofun3, no reason to get reactionary about "sniffy" attitudes. It's really simple: if you like to listen to classical music (at an overall reasonable volume) the lower dynamic range of the music is drowned out by road noise even in a quiet car. You're always turning the volume up for the quiet passages and turning it down on the crescendos, too much of a pain to bother with. Ford's OEM sound systems once had a compression switch to ameliorate this problem. Sure it detracted from the ultimate audio quality, but it made listening to classical music on the road pleasurable.

Brf,

Thanks for the tip about the tires.

Bought a 2011 Accord with the intent of installing a custom system.
Favored the Pioneer stage6 CD player DES-99 or P-9, pricey but really great. Add to that DLS speakers and Amps. Their Ultimate TA2 2x100 is a Tube Amp. Coupled that with an A2 2 channel and a yet unchosen 10" Sub/amp.

But before I figured out how I could come up with $3k needed for the system, I first did battle with the God aweful road noise in the accord, and lost. So I scrapped the idea of a high end system in a honda.
( switched to Bridgestone "serenity" tires, then even tore out the seats and carpet and lined all in dynamat, still noisy) Will never buy another honda for noise ALONE.

My 98 Ford Explorer has a very nice stock sound system and a cabin built for it, and is quiet. If it wasn't so old and beat I would consider a high end system in it.

AM radio

BMW 330i Coupe. Superb audio system. Radio has HD capability. Use aux/USB input for iPod or iPhone. Sounds grand. Only problems are BMW has a custom cable with dual USB and aux inputs which must be used simultaneously, and I have not found an upgraded cable to improve sound. Also, run flat tires create a lot of road noise.
