i have a technics su-600. it says in the manual it does 8ohms at 50 wats max output power. but i curently have 3 200watt subwoofers hooked up to it. it powers those 3 subs to the point of them bottoming out at 10% volume if i have loudness and bass on full! how is this posible? its powering 600watts!! it says it can only put out 50watts max. and its power consuption is only 250watts. how does this work? the safety trips when i try to power 1000watts! still how is this old peice of junk doing this? i found it out in the rain on garbage day! and it sounds great. it gets my subs responding perfectly! respond please
