this is my sony lbt-zux10d. . .as u can see it is an rms of about 1200. . 260x4 +80 watts, and max out put at 12300 Watts. . . after about a min of being in my room it gives you heart palpitations and makes my hole house shake like crazy. . You cant rly see it or hear it that good on cam tho. .but i can say that after a week of owning it my roof in my room and my sisters room next to my room is falling off the battens and iv smashed 2 photo frames with it off the wall. . if you want one its gonna cost ya i payed 1750$ down from 2000$ after 7 months it came out in AUS, the max price where i got it was 3000$. . . i highly recommend this stereo to any people that love loud music and dont mind your house falling apart. .the sound is amazing and nothing like any other stereo. . but the one and only bad thing about it is theres no usb or HDMI for movies on this model. .
