Did you find the audio options. Make sure the treble is set to 100%. The bass set to full might sound to strong. Most treble comes from the front speakers. The bass usually from the back. I'm not sure if the rear speakers include a tweeter or not. I have not received my car as yet. I will have a good listen when it comes in next week.

I find most new cars I buy have the bass/treble aways set to mid-range.
