OEM Navigation issues

1st, I would say I had a successful retrofit of the oem navigation into my 2012 GT500 premium shaker, minus a few repining of speaker wires. It works, to a point, but I believe its my ACM that's giving me the problem...
1st problem, my door subs aren't working. They should work, fact the only thing that should work after the retro fit. It is not the amp or the subs. I put my original shaker unit back it, and they work, so leaning towards the Nav unit. Is the nav unit's pin out (for subs) on a 2013 different from the 2012. I have a 2012 harness, but the nav came from a 2013. I don't know how to test the sub output from the unit. I put in an aftermarket amp for the other four speakers and all are good. I put a small amp right behind the climate control module behind the stock radio. Hidden out of site., didn't cut any wires, made a special harness from the old dash harness components.
2nd. problem....I cant adjust the clock. right now, I have no GPS because I am waiting on the splitter harness, so its disconnected right now. Is this the reason I cant adjust my clock?
I see this forum is a little slow now, probably due to facebook and other pages. If anyone can help, I really do appreciate it.

Amp setup is completely different between 2012 and 2013, 2012 needs the rear amp for nav and the front amp only handles the subs, the 2013 the front amp handles ls every channel so you don’t need a rear amp, once you have the splitter and take it for a short drive you other issues will disappear.

so for the amp if I remember the pin outs change so I would check to make sure your sub pinout is how it is supposed to be.

Thanks for the help, like you said, splitter fixed everything. As for the subs, I figured the pin outs changed, having a hard time getting diagrams to show differences...the search continues.

got my subs working, changed some things in the ACM using forscan, now it works. Sounds way better than before.
