I find that with any equalizer whether it's in a car or part of a great home stereo, that the sound is better when the sliders on the equalizer are arranged in the form of a W, rather than just keeping them flat, though with no slider maxed out. Maybe that's just my own personal taste but check it out and see how it soundsI, too, thought my Model 3 stereo sounded terrible when I picked up my car. Turns out it was the EQ settings. The bass and table were maxed out. I reset it to flat and so much better!
