2012 honda accord crosstour, factory radio

I have a 2012 Honda Crosstour w/ the 7 speaker amplified system w/ Nav. I am trying to add a line out converter and need to find out what the proper diagram is. I originally was looking at one for a 7 speaker 2011 accord on Crutchfield, but the wiring configuration is slightly different. Can anyone help? Thanks!

I have a 2012 Honda Accord Crosstour and I am installing a 5 channel amp, sub and components into. I am using a Audio Control LC6i line out converter for my signal. My plan was to simply run the front and rear speaker wires from the factory amp into the LC6i for input, but I am curious if the factory amp has a built in low pass crossover. If so, I am thinking that may give me crappy low end performance for my sub. I do have a single sub channel input from the factory sub though, I am curious if I should feed that into the 3rd channel input of my LC6i, or do I have truly full range signal from the factory deck and wont need to worry about it?

i would say that the chances are good that your highs have a built in highpass crossover because you have the factory subwoofer, but even if id isnt filtered i would still go the factory subwoofer to get the signal for your aftermarket subwoofer this way it will still control the same way from your factory radio. sometimes it can be hard to tell if the highs are filtered because they might only have a subsonic filter that only filters the lowest notes. and it can be impossible to notice by listening to the mids because their design doesnt allow them to reproduce those low frequencies to the point where you can hear them. so they apply a filter to relieve the mid from having to even try playing those frequencies.
