Do you care about car audio?

My Audi TTS has Bang and Olufsen. The previous iteration had Bose.
I have to say the Bose was a better sounding system.
The B&O has less bass and requires high resolution streaming to sound decent.

I really love listening to music while driving, but the B&O has me listening to podcasts more than music nowadays.

The good thing about car audio is that it runs off the battery. In my last car, Toyota Corolla, I installed a Kenwood CD player, Audiobahn amp and JBL rear speakers. It was great for rock and that’s all I listen to while I’m driving. Now I own a Kia SUV and the factory stereo is just OK though I’ve been listening to The Faces ‘A Nod...and The Rolling Stones ‘Exile on Main Street’ constantly. Point being, it’s more about driving than listening and I don’t use my iPhone while I’m driving.
I’d like to install an aftermarket amp, CD player and speakers but there’s a hundred things that take a higher priority, including paying attention to the road.

Acura's had the Elliot Scheiner (collaborated) Panasonic 5.1 DVD-Audio player with surround sound (5.1) capability. I bought my car in 2009 and DVD-Audio's soon after became obsolete. They weren't around for a long time, but I managed to get most of the popular (rock) out-of-print titles through Ebay and other similar venues. The DVD player also played DTS 5.1 format. To this day, the DVD-Audio of Hotel California and Rumors (96 khz/24 bit) in my car sounds better than my two channel analog system - it's that good (the enclosed space in the car obviously helps, but nonetheless the sound is magnificent). 

Though my BMWs had pretty good audio, I've never owned genuinely first rate car audio gear. I also have to say that if I ever heard truly first rate audio in somebody's car/SUV etc., I can't remember it.  Usually, when somebody, like a car salesman or my hippie era VW Van driving buds, wanted to impress me with the audio they'd just crank the volume to Earsplitting Plus.  I also have to say that I like hearing traffic noise when I drive.  It keeps me more plugged in to what's happening on the road.

My infiniti came with a bose system that was horrific.  I can drive 25k a year and appreciate good sound.  A friend who is an expert delved into it with me.  $60k car but not a single tweeter in the whole system.  We then pulled the amp, which must have amounted to 20 watts.  Bose is really a joke using 2 ohm speaker to boost output.
The short of it:  90k miles later and I've been very happy.  We did massive surgery removing all 4 "twiddlers" and installed high end Seas tweeters.  Rewired the whole system (would you believe the entire back end of the car was wired mono?), installed 9 channels of Alpine amplification and a Rockford processor.  It sounds great now.  It will never be able to get a penny out of this if I sell the car.  So I guess I'll drive it into the ground.
I will never buy a car with Bose again.  What's that saying...BOSE BLOWS.
