yeah the other day while i was testin my system, i had a 3 db differnce... i could tell it was louder, but not by a whole lot.. normally i was hitiin around 149 150, testin it out was at 152 153, . i dont know if it double the power, but all i did to get to their was turn my bass up fro the Hu to 0 rather than -3..
