in the front door or rear ? i replaced my back speakers about 2 hrs ago... with some Polk Momo MMC690's i found that 4 wires go to each rear speaker and the 2 go to the sub one is green with a black line and the other is blue with a white line. which is pos or neg i do not know. the other 2 go to the tweeters or mid speaker that sat on top of the 6X9. those wires are are both solid blue one lighter than the other .. this on on my back passenger side then on the drivers side the wires are completely different colors .. the sub wires are the same colors but the other top speakers colors were white and brown.. in all of this i don't know what wire are pos and neg but they sound good.. im going to try a different way of wiring it tomorrow and i will post my results then .. by the way i have an 06 GTP Silver with the Monsoon
