So i was looking around in the garage and came across a pair of chrysler infinity 6X9s. i was thinking about hooking them up in my duster but cant figure out what the 4 wires coming out of them are for

i know they sounded good in the mini van i took them out of before i scrapped it. they have amplifiers on the back of the speakers. i just cant figure out how to make them work


any suggestions?
thanks
