where do output amp wires go

do the output amp wires go to speakers in door or to the wire out from radio or wire from harness kit i have a harnes kit that plugs into factory connector and speaker wires come out of that harness

if you are going to use a seperate amp (not built in to the CD player) to power speakers in the factory location - you will most likely have to run seperate speaker wires, you cannot use the harness for this.
