I've got one just like that. I dunno if it puts out 100amps like its advertised, but it powers everything including strong headlights, an alpine amp and speakers just fine. I have a 350 without AC, but I'm positive it will run a compressor when I get to that. It always squeals for a split second on startup though.

I followed that thread and it was real easy (I did eventually get the MadElectric kit though).
