You say that you replaced the fuses then turned on your amp then the fuses blew? Or did the fuses blow right when you replaced them. If they don't blow until you turn on the Head unit, then i would say double check you sub wiring, and if thats ok, then its an internal amp problem. If the fuses blow right when you put them in, then check the power wire and its path.
