Good stereo setup for an A body?

I throw this JBL speaker in the front seat and connect via bluetooth to my phone. I can stream anything from Apple Music, Spotify, Pandora to movies on Max. When I get to my destination, I pop it in the glove box and the interior goes back to stock. It also allows me to answer and talk on my phone handsfree, which is very handy. It has a good charge life and puts out a decent sound.

I was considering this idea but since I am kind of picky about the sound quality (especially bass) I was certain that Bluetooth speakers wouldn't satisfy my needs in that area.
