What you see is 4 insulators, no telling what's inside
I HATE suggesting this, but if you are serious, MARK all the wires at the PCB so you don't lose track of them and unsolder them all... Did you MARK them so you can reattach in the proper order? Again I'm going to verify that you marked the wires BEFORE you unsoldered them?
OK once they are disconnected from the circuit board we are going to do a poormans hillbilly test... Get an AA or AAA battery... Take one red wire and one green wire and for a brief moment attach them to the battery, green wire to negative and red to positive... Brief moment just a tap, OK? This should make a single speaker 'pop' do this for all the wires so that you can map them all out to the appropriate speaks... If no pop use the other green as I suspect one is left side the other is right...
Once you have them all mapped out using the diagrams CDRIVE and I posted you can implement the mod...
