I recently won some tweeters for a 06 Escape on the Bay.I think they were for the MAC system.They each have a crossover,and a 4 hole feml. plug.My question is ,how do they hook to my radio? I have instaled them on the door,but there is'nt a plug for them in the wireing.The plugs have 4 wires in them,red,black,yellow,black.These wires go into the crossover........Does any one have a wireing diagram of the MAC system that could help me hook these up? thanks in advance ......buikgs1 ;>)
