Hello, I was wondering if anyone could help me out ? my issue is I have a 2014 mazda CX5 grand touring edition thats came with the bose amp package I believe the amp is bad and I would like to bye pass the amp and add a four chanell aftermarket I just don't know what wires to tape into ? if I wanted to replace the factory radio as well and add a amp and also replace the front speakers with a set of components . if that is the case where do i tape into the speaker wires is it behind the factory radio or is it at factory amp location and if that's the case which harness has my speaker wires ? I am adding an image is it the green harness or the black one ?
