There's no acc on these, go to heater controls for ign +, if you find a mute on back of head unit,  only cut into front speaker wires, if no mute join all four. we have patch leads for these over here but I don't trust them. Your factory head unit may well be marked with the pin outs, if so use tel mute, and one speaker output to speaker + and Speaker - from CK3000. You might have to programme the factory head unit but it will bring out the sound and you won't have to cut anything.
