yea, thats all nice, but what i did which might be more complicated was i took the whole radio out, hooked it up that way and ran the thin like 16gauge(blue wire-to turn off and on with ignition) wire from my amp down to the fuse box on the passenger side and on the left you can pop out the panel on the floor and i just hooked it up to one of the fuses so when the cars on, the subs and amp stay on etc. I had the little RCA power inverter(see through green "Peripheral"- brand) hooked up behind the radio instead of back by the 6x9's. Thats just how i did it. My system pounds!!! New 7'' Power Acoustik Double Din installing soon!!!!
