The modern stereo system

I have 4 Pioneer 6x9s in my Bronco, with a Pioneer am/fm/cd/aux input and bluetooth, and a remote! I've been thinking about getting a standalone bluetooth speaker for my Ventura, doubt I would be able to hear it in the Dart with it's Flowmaster 40s.
Does that count as modern?
I have had some crazy multi amp mega power systems before, but now I'm just old and tired. LOL
