That depends on whether you will be running them off an amp or not. If not then it will be easier to do but wont be as good as amping them.
To connect them without amping them its just a case of taking the existing speaker wires off and putting them into the crossovers on the components. Then connect up the midbass driver to the designated section and run a tweeter cable from the crossover to whereever you want the tweeter.
There you go, bobs your uncle, fannys your aunt.
If you want a description of how to do it with an amp then i can do.
