Factury amp connector pin out

2001 Volvo V70 T5

I'm in the middle of installing an aftermarket amp along with Focal speakers. I started looking into how to run new speaker wires, but it’s turning out to be a pretty daunting task. My other option is to run speaker wires from the new amp and tap into the factory amp’s output wiring. The problem is, I’m trying to find a pinout for the factory amp output harness. All the wires are either gray/white or gray/red, and there's no clear way to tell which wire goes where. Does anyone have the pin out for the connector that connects to the speaker output of the amp. Like these two pins are +/- for the rear left door.
