Just purchased a Earthquake Cinenova Grande 5 channel amp. I'm getting ready to unpack this 125 lb. beast of an amp. I'm reading in the owners manual...quote: "To ensure proper operation, make sure that a 20-Ampere circuit is available where the amplifier is going to be plugged. If in doubt, consult an electrician; most homes are wired with 20-Ampere circuits, but there is a chance that the wall receptors are rated only 15-Amperes." It also states that this amp is equipped with a 20-Ampere circuit breaker. I'm guessing I shouldn't try to run this thing thru my Monster HTS 5000 Power Center?? Help....what do I need to do to assure proper operation of this amp? My house was built in 1979, do I have 15 or 20 Ampere curcuits?? I'm sure I need to replace receptor!! Any help would be greatly appreciated!!
