Why do you think you need more power, is your receiver showing signs of distress or clipping? How loud are you listening in dB's and how big is your room.

A second question I have which is a little off topic, is how do you like your new 350v3? Did it replace another sub? I just ordered 2 350v3's to go with my ep600, but my room is massive. \:\)
