So my back speakers really sound bad compared to the front ones. I have one of kenwoods second nicest cd/mp3 player the 869 and it is really awesome but somehow the back speakers found a way to blow. They are not stock either they are kwoods 3-way 6x8s. I thought mabye they sounded bad because i was in the front of the car and the speakers face in killing my treble but they even sound bad when i sit in the back. Has anyone had luck rewriring the back speakers and seen and improvement in sound. They sound like they just get mid and no good treble or bass. I thought about buying some crossovers and putting some tweets right behind the seats facing forward so i can hear the treble from the back. Any suggestions would be nice.
