Yeah that is a difficlult thing to pinpoint. I have a excelon x589 with similar settings. Had if for a month and I am still plaing around with it. It would seem to me to be subjective to the listener. I know thats not much help but just keep fiddeling with it. It just takes time to tweek. Good luck
you need to set the EQ bands depending on what is too loud or too soft in the frequency response. i.e. if the female vocals are too harsh, set band 3 for 4kHz, Q=1, gain=-2 you really need to know what parts of the audio spectrum (frequency) are uneven, and set the EQ appropriately. EQ settings will be different for every car, and for every brand or model of speakers.
