Personally I don't like the RCA connector for power use. Assuming the female is chassis mounted, as it has been on a number of pieces of equipment (DEMI transverters come to mind), that means there's a mating male connector with +12VDC on the exposed pin, just looking for something to short out with. Granted, it may see very few insertions/extractions, but when extracted it exposes a live pin. A pigtail on the equipment with a male connector could be used, making the power source available on a female inline connector. PowerPoles are a much better choice IMHO, and they can be chassis mounted with some insulating shoulder washers, like power transistors & banana connectors often are.
