So I just bought a 2021 Subaru Forester Sport With the Harmon Kardon System which includes factory amp and sub but i need a little more. From the research I have done I need to tap into the rear speakers at the factory amp using a line convertor to the amp I add. I am having trouble finding a diagram or pinout for the factory amp to know what wires i need to tap for rear speakers, power switched and constant and ground. I really just dont wanna take everything apart to trace the wires if I dont have to.

If it has the HK system there is a really good chance that it does have a Subwoofer. Have you located the factory amplifier yet? The speaker wires should be twisted. Is there one pair of twisted wires that are slightly larger than the other pairs?
