Do you care about car audio?

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.

No.

When I had my VW GTI’s in the late 80’s and early 90’s I changed stereos and speakers quite often. With those cars it was actually quite easy to do. My current car is just too complicated and difficult to do myself anymore. I have an infinity system in my car and it is far less than special. Would love to upgrade it but ohlala hit the nail on the head for me.

8 years ago, Mazda lost a sale of a CX9 because the stereo sounded crap and had engine noise piped in for "zoom zoom."

I like audio in the car and millercarbon is right.  Great way to burn money- buying the top audio package from the oem or aftermarket. 
And I won’t pay for a performance exhaust unless it reduces weight.
