Speaker polarity
 

Hello X men,
Redoing my 4 door speakers on the Blue Bomber.

I got ahead of myself and now I can’t find which door wire is + or -.
I haven’t cut any wires. Which one is the positive and negative?

I’m trying to continue to use the factory harness..

Try to take notice on one you haven't removed yet, usually one wire of the pair will have a stripe and one not or some other type of marking or even size of connector. Or get a wiring diagram for the system that you have.
