Yeah, the crossover for the tweeter should be hooked on the stock 5 1/4 it looks like its in a black plastic. Once you see it you will know what I mean.

You check the finial impedance by hooking up a DMM set to Ohm's on the 2 wires that you would connect to the stock wiring. So basiclly run the + from the tweeter to the + of he door speaker so you have 1 single + wire, which is running them in parallel. Then do the same for the - and then once you put your DMM on the 2 wires it should read about 2.6 Ohm if the speaker impedance is correct based upon what i remember.

You might need to solder in the extra wire but its not that much of a deal.

If you have questions once you get everything tore apart, post in here again and I'll try to help and guide you if you need it.
