2016 Honda CR-V Amp/Sub Installation

hello I'm installing a subwoofer and amplifier into a 2016 Honda CRV and a separate 2017 Honda CRV next week and need some help getting a wire diagram. does anyone know the radio wire colors? I'm installing a line output converter, amp, and subwoofer. I could just test every wire until I find my speaker wires and power/ground wires but its going to take me a while being that there is like 5 different harnesses behind the radio with a ton of wires. it would really save me time to have a wire diagram, any help would be appreciated. I have a wire diagram on a 2015 but idk if this will be the same for the 2016 and 2017. I'm by myself doing both the mother and daughters Hondas in one day so anything that can cut install time down I would once again appreciate.loudhouse

If there's a factory sub, get your signal there. Otherwise, I believe the front and rear speakers are the same size, so just tap the rears for signal (no need to pull the deck). Use a battery to "pop" the speakers to find polarity. Then all you need is a switched wire for the amp turn on lead.My ex once told me I have a perfect face for radio.

Directechs has no audio wiring for the 17 or 18 models. Is it a different vehicle than the 16?
