Display Audio with Navigation and Entune 2012 Prius Trim 3

Hello everyone, I am a proud first time owner of a 2012 Prius Trim 3. This is also my first post. I was hoping some of you experienced Prius owners could assist me with the Audio System. I have the Display Audio with Navigation and Entune. I have changed the settings the best I can to get the "most" audio quality out of the system. My previous car had an upgraded sound system and it was great, so that is what I am use to. The stock system in the Prius is decent for a stock system I guess, but it is not what I am looking for or use to. Without changing out the Audio system (even though many people say this is the first place to start for better sound) does anyone have any experience with upgrading just the speakers and having a major difference in sound quality? Thank you in advance!

 

Thank you, I will search for some of those previous Posts.
