I'm in the midst of wiring my radio to an amp with high-inputs (direct from the speakers).

I'm a complete newb at reading wiring diagrams and I can't figure out which wires are positive and negative. See the diagram for my wiring configuration in my 1980. Can anyone tell me which wires of each pair are positive and negative? The pairs are

1) Blue/Red (LR) and Blue/Yellow (LY)
2) Blue/Green (LG) and Blue/White (LW)

Thanks for any help

Also, is the Light Green/White wire my positive power wire?

Polarity in speakers doesn't matter.

Polarity doesn't matter, but phase does.

To put it simply, as long as you are consistent with what you assign + and - for all speakers, you're fine. There are some cases in high fidelity audio where you want some drivers out of phase, but this is not one of them

If you remove the speakers or can see the cones, you can perform a speaker pop with a 1.5V battery. If the cone moves outward, or towards you, you have the + of the battery on the + speaker lead.

Download the JL Audio phone app (I have it on my iPhone, not sure about Android). It has a feature to check speaker polarity. Play your phone audio through the system and hold the phone up to each speaker. It will tell you if the polarity is correct.
