Question regarding channels E n F on these channel's only my equalizer allows for every other frequency band of adjustment is this something that I could correct? My settings are as follows channel's A n B Tweeters, C n D Midrange, E n F Mid bass ( under seats ) and G n H sub. Other than the sub all drivers are in the front and my input is the front right and left out of the stock head unit. All channel's are set as full signal from front left or right output except G n H which are set as sub. Any thoughts?
