Any amp wiring difference between 2013 Sony w/ Nav vs Sony non-Nav?

[edgesportguy]

I built this unit to fit in front of the spare tire for my leased 2013 Sport w/o Nav and am getting ready to put it into the one I bought with Nav. A single 5 channel amp would obviously be much easier but I already had the JBL Crown and it's an amazing sub amp. Does any one know if there is wiring difference between 2013 Sony w/ Nav vs non-Nav? I searched and couldn't find anything

 

The dual 12" Boston subs are a bit overkill but I listen to mostly hard rock and absolutely love a hard mid-bass punch (not muddy, distorted, annoy the neighbors type bass). The JBL GTO 4ch puts out about 100rms and JBL Crown amp was driving the subs reviewed at about 630rms so the system sounded clean and pretty amazing, gives you a massage when the bass hits, and makes your hair tingle on the occasions that I regress in maturity and crank it way up. I'm probably going to go with dual 10" Alpine TypeR's this time around,

 

Maybe a dumb question, but has anyone tried a 10" & 12" Sub combination to get a hard, tighter mid-bass punch while keeping the nice lows? The reason I ask is because I have one of each Alpine TypeR, and it seems to make sense in my mind. If I do this I'm going to build a single custom box with subs pointed in slightly different directions since I found the single 10" against the seat aimed straight back but the 12" in the rear most drivers corner pointing slightly forward at a diagonal, Should I run one channel serial or 2 parallel? Both subs are 4ohm and the JBL Crown is 1ohm stable so I can run either set up
