I just installed a new box for my friend. When I went to tune his amp for him, I noticed that his subs were moving out of sync, and one was moving a little bit faster than the other one. The subs are two Rockford P3's and the amp is a Rockford P1000-1bd. Both subs are dual-4 ohm wired down to 1 ohm. The box is a dual-chamber ported box tuned to 30hz. I've tried reversing the polarity of one of the speakers but that only put it further out of phase. They seem to be hitting alright, but I can't help but think that something's not right. Any suggestions?
