John John,
Here's the scoop! I presume you have a rack case for all of your gear. If so, Mount the amps (Heaviest stuff) in the bottom, if you have spaces available leave some for ventilation. The player outputs will go into the line inputs of the mixer. Depending on which mixer you have, it will probably be line 1 and line 2. Your crossfader assignments will determine what goes where.
The output of the mixer goes into the crossover. Low out goes to the amp driving the subs and hi output goes to the amp driving the top boxes. If both amps are the same it doesent matter, but if one has more output , use it for the subs(low-end). Check the specs for the speakers but if the tops have 10" woofers, set the crossover to 200-250 HZ (cycles) if 12" use 150 HZ and if 15" use 125hz. You will most likely need 4 speaker cables, 2 for the tops and two for the bottoms. If you make your own, please double check the polarity of each cable (White or red to Positive and black or clear to negative) so the speakers both work together instead of fighting each other (out of phase).
Good luck!
