you dont really need to break subs in for spl purposes. BUt if you youre shooting 100% SQ then it's you should break them in. But yeh it's not needed for a sub to break in. The longivity of a sub does not depend on breaking a sub in. So subfanatic is right
your also right bass lol...if you wanna make sure they sound awesome break them in...but 10 hrs should be enough..now just start rising the volume more and more over time
Yehp, it isn't really needed. I also noticed though when my sub's wher brand new they didn't sound that good, or hit that hard. Then after about 2/3 day's, they wher bumpen, and sounded grate. My advice is just play them normal for about 2/4 day's, then you can do what you want.
