I'm sure this has been asked before, but i've been unable to find an answer. I am looking to replace the head unit with the bass/treble sliders with the unit with the 7 band graphic equalizer. My old 00 GT had the graphic equalizer head unit and it sounded pretty decent for a stock system. I'm sure aftermarket would sound better but it is out of the question due to numerous theft problems in the past. Are these units just plug/play replaceable/interchangeable? Just wondering what the difference is in these two sound systems. Thanks in advance!!![]()
