Before I sold my old truck I took out all of the audio stuff out of it. Now that I have reinstalled it in my new truck a few months later, It seems channels 3 and 4 no longer work. I am sure they worked when I uninstalled it. Amp is a alpine mrp-f300 bridged running image dynamic components. Any ideas? Switched the rca cables back and for so thats ruled out.
