My reciever is the typicaly 100 watt per channel output but I have L&R speakers that are rated at 300 watts but only singular inputs (biwiring?). I am worried about damaging the speakers from underpowering. What is the best way to solve this? I have my older kenwood reciever sitting around. Could I tie this in to add power or am I going to produce feedback and really screw myself? Thanks for your help everyone.
