power supply for car amp

Here's a diy power supply, capable of 13.8V @ 10 A continuous. It's an Australian site, and we have 240V house supply but Rod Elliot, who writes all the (great) stuff here usually has notes for whatever supply you have. I think this will be a little expensive to build because of the heavy duty components but hey, if you had something with this much power retail it'd probably be better economy to just buy another amp designed for ac supply!
