Chrysler Lebaron 1988 speakers wiring

I, i have a 1988 Chrysler Lebaron and i'm trying to replace a door speaker that is missing.
The problem is there are 4 wires for the speaker :
Wood Automotive tire Bicycle tire Kitchen utensil Auto part

With the diagrams available on internet i found that the pink one was the positive and the blue/red negative but i don't understand the other two.

Following the following diagram the black/green seems to be connected to all other speakers, and a ground on the radio (X15)

and the black red to the other speakers too and a "radio choke".(X13)

Font Parallel Rectangle Slope Symmetry

My question is : Do you think that the positive is connected directly with the choke and the negative with the ground, meaning that all speakers are connected together ?

I really don't understand this wiring

Each speaker gets connected to the radio with + and - sound feed. Then, in the premium Infinity system, each speaker also has power for the amp. All speakers can share a common power and ground for the amp, but have separate power and ground for each channel of the radio (RF, RR, LF, LR).
Many Chryslers used a central amp, and many had separate amplifiers on the speakers. No idea how they decided which to use in a given application, I think the first application was a central amp driving only the rear two speakers in the early 1980s.
