This is a great forum! I can't seem to find an audio wiring diagram for the 2012 Honda crv through the search. I am looking to tap into the accessory 12v power wire and the rear speakers (+ and -) to add a sub.
Thank you for you time and knowledge.

If you're running a sub, use the power antenna feed, Gary has kindly listed it for you.

There are 4 harnesses connected to the radio:
A large dark grey one, a smaller dark grey one, a white one, and a small 2-wire lt. grey one.
I'm having trouble matching up the colored previously provided. Which harness is the "radio" harness, and which one is the "power antenna"?
Thank you for your help

TEST!! Look for the black as mentioned to go to 12V+ when the head unit is turned on.

Tested. Red appears to carry the 12v constant on the large Drk. Grey connector (with a clear sliding tab on the top of it) the Black below that is the ground. Purple is 12v switched. White did not provide 12v for me in any ignition mode.
Hope this helps someone else!
Thanks everyone!

jus10sticks, can you describe the process to remove the OEM radio to get access to back connectors. Thanks.

By the way, I think the wire you are looking for (power antenna turn-on) should be in the small gray antenna connector. Test it when plugged in and radio on AM or FM source.

If the antenna plug is white, small and round and looks like a satellite antenna plug, it's called a Fakra and carries the voltage through the plug, plan B required.

Can anyone describe the steps to remove the radio and get to the back connecors on the 2012 CR-V? Do you have to remove the air vents first or the climate controls?

If anyone else comes here looking for the wiring diagram for the 2012 Honda CRV, the second post which describes the colors is incorrect. Jus10sticks is correct with the rear speakers and the accessory wire. I have a 2012 Honda CRV LX and just installed an amp and aftermarket speakers. I will put up a few pictures of the harness.
These are the speaker wires and the accessory wire(purple).
Top row of dark grey connector (From Right to Left)
1 Black ground
2 Blue rear left +
3 Pink rear left -
4 empty
5 empty
6 Blue rear right +
7 Pink rear right -
The purple on the bottom left is the accessory wire.

Here is a pic of the other side of the same harness which houses the front speaker wire.
Top row (Left to Right)
Red- Constant power
White - Left Front +
Black - Left Front -
Red - Right Front +
Green - Right Front -
Purple - Accessory
Hopefully this helps others looking for this information.

I just wanted to make a post to confirm that elmortero's diagrams are 100% correct.
I just installed an amp and sub using a cross over and stock radio adapter kit.
Everything is working properly and 100% as intended.
Thanks, elmortero!
