Componet speakers tend to sound better than ones that are all together, such as a 6x9. A componet speaker consists of a tweeter, midrange (which can be a single speaker anywhere from 3" to 6"), and crossover. On the stereo instructions you will have a positive and negative connection going to one speaker. In the case of the component speakers, the two wires will connect to the crossover input, then four wires will come off the crossover. Two to the tweeter (positive and negative) and two to the midrange. If you are using the amp, it will go between the stereo and crossover.
With the list of components you have, I would dump one of the two channel amps. Bridge the other one to send the full 200w (incase of the Kenwood) to the one sub. Use the 4 channel to power the front componets and rear speakers. Which brings up the rear speakers. Personally I would add a tweeter to each 5 1/4 and a crossover, or just use the 6x9, but not both.
But basically starting with the head unit, you would connect the speaker wire from there to the eq, the eq to the amps, the amps to the crossovers, the crossovers to the speakers. The only variation, is if your head unit has RCA (pre amp out) connectons. You would connect those the eq if it has the same inputs. This might have opened up a bunch of other questions. The RCA connection would be preferred way. They are low level outputs that help to prevent outside interference from being amplified in the amps.
Not sure if this is really what you needed, I might be able to help with more specific questions.
