Just got an accord 2015 LX and well the sound system blows. Read about some people changing dsp flat to on through the developer menu but that was for different trims. Anyone know if this works for the LX? Is there anything else I can do to improve the quality? I would like to keep the factory head unit because of the ability to use the iMid (rear view camera screen, gas mpg and range screen). If there is a way to keep all the functions and the iMid screen, I would upgrade my head unit. I know that upgrading the head unit alone to something that has an eq, lpf, hpf, etc will do wonders. I just would like to keep all functionalities. I read that you could bury the factory head unit behind climate control and install a new head unit and keep all functionality. This seems extremely complicated and might not be worth it for me. I've also read about disabling the ANC module. Will this improve sound even if everything is stock? This seems to be a solution for people who have added a sub.
