Im new here, and barely got my hands on a silverado, well yesterday i was cleaning up all the wiring the previous owner had in terms of the stereo, i clipped and re connect all the amp wires all grounds everything, and also put new speakers in it, well everyting worked fine till about awhile afterwards then all the door speakers stopped working only the subs are producing sound i checked the fuse from the stereo aminute ago and thats fine and the HU still works.
i need help diagnosing whats wrong..
