Hi guys. New yukon owner here. Picked up an 05 denali with the bose and factory navigation with RSE last week. Wanted to add a backup camera to it, and well, after reading around the web and researching decided it'd be more cost effective to update the headunit/nav in addition to adding the backup camera.

This leads me to where I'm at now. Picked up a clarion nx404 with the gmos-014 and awsc-01. Got it all installed and went to test it out and found that i'm only getting sound from the rear two door speakers. When testing with the fader/balance, i've found they're acting like they are the front speakers. So this has me wondering what i may have wired wrong.

I wired the clarion harness with the gmos-14 16 pin adapter wire for wire almost (all the colors matched up for the speakers, power, etc) and only had the power antennae left over.

I noticed on the 20 pin adapter that there are two very long green and two purple based wires on them with what seems to be some resistors in them. From what I could understand from the terrible instructions, those aren't applicable for my setup.

Can anybody maybe help provide some insight to my issue?
