2012 Prius subwoofer install...rear speaker taps?

I'm trying to install a sub and could really use some help....not sure if the LOC is bad or if the taps from what I believe to be the rear speakers, tapped from behind the front driver side and front passenger side seatbelts, are not going to the correct colors.

Anyone have some diagrams, pics, knowledge, or links to any other relevant info?

I've searched a bunch but haven't found anything to exactly confirm this....just info on tapping directly from the stock head.

Any info greatly appreciated!
