schematics

Hi, I recently purchased a 2015 Honda CRV EX. The sound system is pretty bad. So I wanted to add this under the passenger side seat: Kenwood-KSC-SW11-Compact-Enclosed-Subwoofer My questions: 1. How to best hook this up? I want to tap into the 12V accessory power adapter that is in the arm...

All i need to know is the color codes for the wiring in the 2007 standard radio(no navigation). I can't find them anywhere and i already have my dash dismantled and my mini sub 90% installed. Can anyone PLEASE help??
