MG4 massive sound system upgrade - Speaker City

[jamakr4]

I installed this 4-unit fuse box in the same compartment as the vehicle's original fuses.
The subwoofer is powered by a 10A fuse, so that cable needs to be fairly long.

My fuse for the DSP and Sub is directly behind the 12V Battery terminal as I needed to route an extra 12V Battery connection.

Mine is also connected directly to the battery, but let's say that with that circuit breaker I isolate myself in case there is a problem with the "4 units" fuse holder that powers my things.

I got the idea for the tweeter in the rear door from MAGOULASFABRICATIONS and Alan Kemp, who has two excellent videos.
The subwoofer is a Pioneer TS-WX140DA 50W RMS. It looks small but delivers good bass.
The external control allows for quick adjustment of frequency and power, and being able to hide it under the seat makes it perfectly compact.
The speaker kit I used is a Hertz DSK 165, which I modified the crossover to my liking because I found it too shrill. It's good speakers without spending a lot of money, and it's a world of difference from what I had before. I integrated the 6.5" speakers into the original brackets, breaking the original ones since I wasn't sure how they would fit with others, especially considering the height/depth.
The acoustic foam inside the door is 2cm thick and the adhesive aluminum is 5mm. If I had to do it again, with what I know now, I would choose something thicker. Also, since I had leftover foam and aluminum, I soundproofed the rear trunk door, effectively isolating the entire car from the outside. The difference in noise and temperature is very noticeable.
Here you can see my process, although it's in Spanish.

I'm struggling a bit with preparing for the install.
I think what I need to do is cut the RCA plugs off the cable that pioneer supply then "tap" them into the :
Left

• White/Yellow
• White/Brown

Right

• White/Orange
• White/Green

in your picture.

then black goes to earth, yellow to positive on battery... but where does the blue "remote" go?

**Edit: I dont have an amp. I'm just adding this to the system (well thats my intention anyway)

Hi.
I've attached the Pioneer TS-WX140DA Subwoofer manual, which shows the electrical installation.
The colors you mentioned are the audio outputs to the door speakers, you only need one channel since the subwoofer is mono.
There are two connection methods: one via RCA if your multimedia system has that "filtered" output (which isn't the case with our MG), or with a line cable +/- to a speaker, that's how I did it, those are the colors you mentioned and I marked them in the image.
My job is repairing PCBs, and I'm quite good at stripping wires and soldering with tin, a bit of heat-shrink tubing and it's perfect.
The workspace is a bit cramped, but with patience, it's easy. The most tedious part is routing the cables and removing the glove box the first time you're unsure how it all works.
The remote cable "blue" doesn't need to be connected, this subwoofer activates as soon as it recognizes an audio input and works very well. When I open the car door, I always hear the Welcome message, and when I close it, it automatically shuts off.
I don't have an amplifier either, I have more than enough power from what the vehicle delivers, but I was missing the subwoofer part.
I've also attached an image of the electrical installation I did.

*/ The audio diagram is for a Trophy model since it has front and rear speakers, but I think the colors are the same.

Let me know if you have any further questions.
