Help identify audio wiring harness - base USA X3 pins.

Attached is the wiring harness pairs and colors for my 2012 12 speaker hi-fi system. Can I get help identifying which wires are for what, please?

I assume that pairs 10 and 11 which are thicker are subwoofer this right? I assume that 23, 24 and 25 are 12v power, ground and something else.

That leaves pairs 1 through 9 as wires for the left front input, right front input, left rear input, right rear input, front door left speakers, front door right speakers, rear door left speakers, rear door right speakers, and center channel speakers.

Can I get some brainpower for confirmation of just what is what before I tackle my possible upgrade?
