got a 91 caravan with the infinity system and the radio was stole and they cut the wires and took everything leaving me with one hell of a mess....

i have everything hooked up exept for 3 wires 1) black/yellow 2) green/black 3) green red ..... all works just no sound is my problem

now black/yellow is just illumination i think so that eliminates that wire

the green/red i think may be the amp trigger wire, would the green/black be a amp ground wire?

how can test this before hooking it up?

thanks

o p.s where would the amp be located?
