Alright I think I can at least run one cornwall. The amp I have is a sony STR AV480 110 watt AM/FM receiver. a link to one is here http://www.hometheaterforum.com/topic/239188-fs-sony-str-av480-home-reciever/ all I know is that it sucks and it was cheap. Can it power 1 cornwall without damaging anything?
