Hello,
I bought a 2017 Subaru Crosstrek, it has the factory stereo without navigation. I like the features of the stereo, it sounded OK,.
I just installed the Kicker upgrade speakers and Dash tweeters, WOW what a difference. I have plastic bowls that weigh more than the factory speakers.
Turned down the virtual bass, as it is no longer needed, so much clarity and sound. It is a great upgrade.
For comparison, I have high end Kenwood stereos, JBL speakers and powered subwoofers in my truck and PT cruiser and the Subaru now sounds 85-90% as good as the PT cruiser and my Truck.
