Do you care about car audio?

Even the finest car stereo does not compete with a good home system. 
Playing loudly enough to appreciate a high end car stereo is at the least distracting if not isolating.  Both are dangerous.
Drove over 6000 miles in 16 days and did not listen to the Porsche/Bose stereo at all. Glad I did not spring for the Burmester.

Car audio is something that you improve only if it really bothers you - it is something that has to be just good enough that you can listen to it without wincing while driving to where you have your real system at home.

There is a valid argument for upgrading speaker drivers as the stock ones are almost invariably cheap and easily improved, but beyond that, why bother. (and I say that as a guy that drove his late 1960s Lamborghini with the original 8 track stereo still installed - every time I went for fifth gear, it would push the tape in and start playing).

Comparing home and car audio is like comparing a 911 turbo and a Hellcat, they both do the same thing, just differently. 
I’ve never personally been so distracted by listening to music to loose situational awareness, gave me a chuckle, thanks for that. 

I just realized something reviewing this thread. At 49 I’ve had 42 cars total, I have never put any major stereo system in any sports car I have owned. In retrospect I subconsciously must have wanted to be in tune with the driving experience rather than separating from it. 

MAN! Remind me never to drive with most of you!  Road noise sucks!

To me, one of the greatest joys of living in the modern world is driving and listening to music.  Loud!  I'd much rather have a hot car stereo than a hot home stereo, but luckily I've got both.

I had a car stereo last me through at least 5-different cars and never regretted it for one minute.  I continued to upgrade it along the way.  One of the things that made this work was that I had a fantastic installer that I met at one point that made this all happen really well each time I changed vehicles. 

The installation of a car stereo is by far the most important part.  A good installer can make low-end components sound fantastic and a lousy installer can just destroy the sound of the highest end components.  Car stereo is extremely install sensitive!
Now I have a Tesla M3.  Because of the way that car is I had to move an integrated stereo that operates off the stock GUI in the car.  It operates just like the factory system did, and you can't tell that there is a custom stereo in the car, except for the sound.  Most of the speakers have been changed and a sub added.  It's fantastic, but I had to go to D-class amps for the low amp draw.  It's a bit of a compromise from my last system which was using McIntosh amps and had a more delicious sound.

Man, get off the pod-casts and talk radio and put some kickin' tunes on!
