Installing clarion vx401 into my 2008 impala, have the gmos-lan-02 interface.

I have it all wired-from what i can tell-correctly.. but when i plug the deck in, and start turning the volume up the speakers cut out front to back-tweaters first, then front door speakers, then 6x9's in rear..

This is my first deck install since the good old days when it was just a few wires to splice together..

any suggestions? will give as much info as possible if need be.

 

if you dont blast the volume do they cut out?
