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 :

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)

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

It seems to be a power supply for the speakers, maybe for the infinity system, but if i put universal speakers, do i need to wire this power ? It looks dangerous

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).

Ooh thanks a lot, so i just need to connect the positive and negative and insulate the others wires

The positive and neg are powersupplys, not music.
its the connections at the speakers named 2;3 thats carries the sound.
- but these are probably low level signals unlike ordinary speaker signals so basically it wont work.
You will either find a speaker with th ecorrect amplifier built into it or convert the system to highlevel all out.
- basically changing the head unit to something more modern and rewire the speaker system, there might be options for connecting the headunit to an amplifier. ( and thus keeping the original look.)

There were Infinity amplifiers used in 2000s Sebrings, they split the audio output into 6 signals, dash L&R, doors L&R, rear L&R. They are usually under the passenger seat on the convertibles.

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.

The parts catalog shows a 4-spkr & a 6-spkr system.
The 4-wire speakers would have an amp circuit board on the spkr. The RF door spkr should be a match for the LF door spkr. Look for a Mopar # 4300174. Coupe (21) & Convertible (27) used the same part.
Someone tried to modify the old spkr wiring?
