The system in this car seriously sucks. Fender (first car I test drive) or OEM to me sounds equally harsh. I was able to change the frequency of the mid equalizer to 4K with OBDEleven, it alleviate the extreme mid-high harshness, but still too much for my liking. If I decide to upgrade the system in this car I'm just going with an Audio Control Matrix amp and aftermarket separates.
