Hello, I have a 1993 pontiac trans am, i installed a alpine headunit and removed my center speakers(4/12) and installed new ones,but they dont play now.the old ones had plugs, driver side has a green/black and blue/white wire, passenger side has green and blue/black or blue only i think. I have 2 fronts, 2 center and 2 rears, centers were the ones i removed. In the head unit i wired, green with green, green/black with green/black and so on for gray and purple. then on the hu's side there is 1 blue cable titled power antenna so i wired that with power antenna from the cars wires.and there was a bluewhite wire from cars side that i left unconnected. dont know if thats right,but everything works except for those two speakers, so i dont know,please help. and the speakers have one wide and one thin connection prung, how do i make them work,thanks.

You have 4 speaker outputs on your HU and 6 speakers in your car, two of which are not working.

Am I reading this right??
