1) Remove the grille.
2) Access to the woofer is accomplished by gently prying the trim ring out of the counterbore, which is attached with a friction fit, using a small, flat-blade screw

driver or similar tool. The four Phillips screws will then be visible.

3) Access to the HF/UHF sections and crossover network is accomplished by first extracting the upper four rubber grille retainers; this can be accomplished by 

carefully pulling them out of their cavities with long-nosed pliers or a similar tool. Phillips screws will then be visible (power tools are not recommended here). 
Remove the four screws, and then pull off the faceplate w/UHF driver attached to it.

4) Access LF, UHF tweeter, or crossover network as needed.
5) Woofer Replacement: Make sure the woofer is exactly centered in the counterbore, otherwise the trim ring will not fit in place.
