you say speakers how many speakers are you hooking up... is this amp a 2 channel or 4 channel amp?

if its a 2 channel amp with an O/P of 45x2 RMS and you are running speakers that recommend 100 Watts RMS then yes you are underpowering them....

Realize, of course, that "underpowering" won't hurt anything as long as you don't overdrive the amp and cause clipping. What is the make/model of your amp and speakers?
