CD power wires

I have a 1994 Honda Prelude Vtec and the stereo that was in it was stolen recently, cut out to be precise, so know I have to ground wire the whole stereo instead of using a handy wiring harness. Anyway I am trying to figure out what all the colors are and I know all the speaker wires, but I am now down to the 4 power wires; red, red/black, black (which is ground obviously, or at least I think), and white/red (which I think is accessory. If you have any help or confirmation on the wires i've listed, it would be FANTASTIC! Thanks
