So i changed my injecters and in results my radio is skipping power like it cuts

That's not a bad way to find an open circuit, but if you aren't successful there, you can always look around online and find a wiring diagram that will help you track which wires back there go to the stereo. Also, you should look at the fuse for the stereo and make sure everything else on that circuit is working... could give you another clue. Find out what you snagged and fix it.
