IME 100 watts is plenty for the 1.7. Since its a 4 ohm load, that means to make 100 watts the amp has to make 5 amps.
That's a far cry from 40 amps... in the case that you mentioned, the 40 amp spec has nothing to do with amplifier power. Instead, it is the amount of current available if you short the power supply for 10 milliseconds. IOW, its a measure of the power supply capacity.
