Rear speaker wiring
 

I have a 2017 base model so it doesn't have the rear speakers. I've upgraded the deck and this spring I plan to add the 2 rear speakers. Does any know if the wiring is already there? I hear this sometimes happens to simplify manufacturing but not sure if that's the case. I can't check so thought I'd ask.

no wires.

Nope, you'll have to run them. Which because of their size I find installing the rears kind of pointless.

I have a bose no Nav, anyone know the polarity on the rear speakers wiring. Looked already but find different answers
