how do i open the MM6 Crossover??

Systems

Hi, i just purchased an MM6 6.5 component kit, anyway, i read the manual right now because i'm going to install these speakers in my car tomorrow, it says to "Remove the yellow crossover cover by squeezing the cover at the tabs" well, i cant find the tabs, i don't know what to squeeze and i cant open up the crossover to make the connections, i don't want to break it so could someone help me out a little. thanks
