Amount of time to get six pack abs?

i workout my abs every other day and i have a body fat percentage of 11% (of course that's good). anyhow i just started working out a week ago and i i can faintly see them coming. how long until they are perfectly visible and rock hard? i generally play football(soccer) everyday so i don't need to incorporate extra cardio. thanks. by the way I'm 15 if that affects anything
