A:Answer The 165 watts refers to your left/right, center, and surround speakers. That is the power that the unit's amp channels provides to those speakers. Subwoofers are many times self powered. Keep in mind that it takes a whole lot more power to drive the bass frequencies than higher ones. These AVR devices are designed to give a line level output to drive a self powered sub. The self powered sub woofer's output depends on the amount of bass/lower frequencies you wish to hear and feel. Of course, budget comes into play, but if you want serious kick, you will want to consider 600W or better to rock your world.
