Hello... I have 225 watts going to the highs/mids, and 250 watts to the lows in a passive bi-amping setup to my front/rear NHT VT-2 spks. What is the total power output to my spks? Is it the larger number being sent to the lows, or is it the combined total of 475 watts to the spk? No one has been able to answer this for me. A 5x200-ch amp is sending 200 watts to each spk, what am I sending? Anyone!!
