LOL Yes I checked the fader (Never hurts to ask tho) Been known in the past to do something like that. Once I hooked up harness I have a Blue and an Orange wire left on the after market harness. No one seems to know the issue someone said it sounds like there is a factory amp however its an Aveo5 ls very minimum additions. There are 2 more color wires running in the factory harness tho one is white with red stripe which on top of factory stereo is a Remote Ground. And then a Green with red strip that says Remocon Front Signal
in the after market harness nothing pins to these. Just really confused!!!! Ready if I cant figure it out to just run new speaker wire for front speakers and wire directly to the New Head Unit Harness. I have never had this issue before I have hooked up quite a few radios for people with Aftermarket harnesses.
