So I just picked up my new ST3 on Tuesday. I had a 2012 Ti sendan before that with the Sony stereo in it. The stereo in the ST sounds so much better! The door panels dont vibrate, and the bass is so much heavier! I dont even have the bass turned up all the way and its still almost too much. It also goes much louder without distorting. Does anyone know if there were any upgrades to the Sony system in the last year or something ST specific?
