Front door speaker wires

[Mountain boy]

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.

Left Front -> Blue & Brown/Blue twisted pair. 

Right Front -> Yellow & Yellow/Black twisted pair. 

 

Just fyi though, some trucks somehow have slightly different colors for the speaker wires, mine included. I don't know why. Above though is what's in the GM electrical manual. You can find it here -> https://www.gmupfitter.com/pages/body-builder-manuals

Thank you very much! I believe the amp for the Bose is on the back wall, so the wires run to the front. I have to put the bass blocker in front of where the factory sub is tapped into the right front door wire.

You are welcome. Yes, i believe the amp is in the back wall and the speaker wires run in the "cable channel" under the driver/passenger sill.
