Does anyone have any specifications for the amp or the sub used in the 12 speaker Infinity system? All I know about the sub is that its an 8" DVC. Is it in a sealed enclosure? Sensitivity? Wattage RMS? And for the amp, I read that it can do 50 watts to each channel but at 10% THD, which seems pretty bad. What is the RMS wattage @ 1% THD?
