When you pull the stereo out you will have a wiring harness plugged into the back. This harness is normally in two sections, one is for the speakers wires and the other is: constant 12v power, ignition power, ground, telephone, electric aerial (if applicable) and remote cable (if applicable).
In my experience the ignition cable is normally the yellow wire but I have no experience with Honda so I couldnt be sure.
I dont even know if the stereo has pre-outs to fit an amp to be honest but I'm sure you probably have more information on this than I do.
