I fly RC helos and in that world there is a definate break in period on the batteries. For the first few cycles you don't want to work the batteries too hard but in this case it sounds as if you just need to connect the speakers and enjoy them. The sub on the other hand I had figured that maybe the components are a little stiff initially being that they are much larger and need a little exercise before they start to really sound good. I figure I'll just connect it all up and start the concert. :-D
