Wiring speakers to a 4 channel amp, just the door speakers and the rear speakers Options

[secra12]

Once i get my tweeter covers in the mail, im going to be rewiring my speakers to a 4 channel amp. Has anybody else here done this? I already have my Kenwood wired to 2 12" kicker comps in my trunk with a bettery powering an audiopipe mini amp in my trunk (yes my car runs off 2 batteries-stops my headlights from dimming). I have an 8" speaker in each door(idk the make/model as i got them from a friend that moved recently)and he also spliced in tweeters from the speakers. In the rear i have 2 sony explods installed (not sure of the size b/c the previous owner had them installed).

This will be my first attempt at wiring speakers and i have no clue really what im doing. Can anybody help?

I have already bought 16 gauge speaker wire and another set of rca cables. All will be wired to an older 4 channel Sony amp until i can afford a newer one.

One way that comes to minds that you can try to put the wires through the jacket.
Find the factory wire that is now attached to your 8. Cut it on the side that is in the car and to that end connect the new four wires very securely. Then start pulling from the inside of the door so it goes all the way through and you see the 4 new wires.
