Does the basic radio have rear speaker outputs?

Ok. Does the factory wiring just "Y" off to each speaker or does it have a separate dedicated output cable for the door speaker and the dash speaker? If if it uses a "Y" I should be able to connect the factory door speaker output cable to the crossover input and then the crossover woofer output to the door speaker and the crossover tweeter output to the tweeter and just abandon the factory tweeter cable. This would allow the crossover to be mounted in the door and piggyback the crossover tweeter output cable on the large factory cable harness serving the door and then to the tweeter. Is this the way to go?
