Wow man you got me so excited I haven't had nice subs for 8 months now, and they were in a horribly designed sealed box, so holy shit i"m happy, how would you break them in? keep the power lower for a bit?
Breaking in a sub takes roughly two weeks. Crank it up at times for two weeks and you'll be fine. They can take a 1500 or a 2500 with no problem.
