This sub sound amazing right out of the box. No need to break them in at all. I'm 100% satisfied with my purchase and I like it cranked up all the way, and there's still no distortion. I have an old school kicker 800 mono black to power 2 of this. You can not go wrong with this and I don't want to say for the price, because I mean it at all.
