I'm looking to build this circuit here, it's a simple 22 watt audio amp:

I understand the circuit for the most part, but any advice/knowledge on the following would be great!
1. Regarding inputs, how would I go about hooking up a single mini jack input? It wants RCA inputs. I know radioshack and the like carry those 1-2 adapters, but is one really necessary? I guess if I knew how they were wired i could make my own...
2. I like this circuit because it is so simple and because it is 12v. It pulls 5 amps at full power, and I'm curious as to how I would go about figuring out how long various batteries would last, or if I would be better off getting/making a power supply. If anyone knows any equations or any online resources in this area please let me know.
