yeah the W7 is pretty bad, BUT THE PRICE IS OUTRAGEOUS!! and my system with 2 12" hyper pros and a 1500w Power Acoustik amp will shake my neighbors house (and we live in the country). Trust me it is loud... and rf runs too stinkin hot! my friend before he went Orion had some Infinity subs and a RF amp and it would shut itself down about after 2 or so hours, and that is not at full volume and within the amps ability. (it was rated at 4ohms bridged, and guess what he was using 4ohms bridged). The amps was also in the back of a truck (single cab) with good enuf ventilation....
