What do audiophiles do in their cars?

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.

Nakamichi head unit. Genesis amps x 3 Soundstream subwoofer.Audio control  Active crossover .van den hull cable .  DLS speakers.   Bat cap. Sound deadening material.  But then I grew up and concentrated on home audio.   Now I hardly ever listen to music in the car. 

bishop 148.  Focal not bad.   All depends on your budget .   But then you might want to upgrade the amplifier
