On black Friday I bought a Sub-10 at BestBuy. Yesterday (12/8/06) it stopped working. I could force the blue light to come on, but the sub would not make a sound. When I used the auto setting, after the requisite 15 minutes the red light would come on. I tried the auto and on settings and turned the volume all the way up. I was using the LFE input. I have a Pioneer 1015TX and it was not at fault. I hooked up an Infinity 8 inch sub and it worked fine. I made a quick trip to BestBuy and exchanged my Sub-10 for a new one. It works for now, but I am nervous.
