Can any give some insight on which wires are connected to which speakers on the green plug. I have attached a picture. There are a total of 10 wires and I’m assuming they are (LF+/-)(RF+/-), (RR+/-), (LR+/-) 12V and ground but do not know which goes to where. Any help would be appreciated! Thank you!

I have never liked the bass coming from the Bose door speakers in my AT4. I installed the factory sub and turned the bass down to -12 on the infotainment and up on the sub, better but not happy still. I bought a couple of PAC BB -1PR bass blocking caps on Amazon $9.00 they are small and go on the hot side of the input to the speaker, right yellow left blue. I cut the wires in the door floor panel tray and just put them in with red butt connectors. The sound is so much better it cuts out 0-300 on 4 ohms and 0-150 on 8 ohms. Not really sure which they are but it works. I can now set the bass to 0 in the infotainment center and turn the bass on the sub down quite a bit, maybe to half. The sound images much better and the mids and highs are much more crisp without all that muddy bass. A huge improvement for $9.00. I want to get in there with a real time analyzer soon and finish it up. The factory sub sounds much better now.

Does anyone know the color code of the speaker wires for front door speakers in a Bose system. I want to put filter caps on the speakers to take the bass out of the door speakers. I have a sub so don’t need the bass in the doors. I don’t want to remove the door panels if I don’t have to.
I have a 2013 GMC Sierra 1500 SLT that I just bought and I am looking to hookup an after market subwoofer and amp but I like the stock dash look so I don't want to replace the stock radio (which would make this process a lot easier). Would I just replace the stock sub and amp and splice into the current wires? Could I keep the stock sub and amp also while connecting new sub and amp? Does the stock radio have RCA connectors in the back that I can connect too?
In a perfect world I would be able to add a new sub and amp without replacing the stock sub and amp and still have a high quality sound system without using RCA plugs since I do not think they come on the back of the stock radio.
