I have recently installed a new stereo in my truck and I cannot get it to function properly. I installed new speakers all around a new headunit and an amp and sub I had laying around. When I turned everything on I had popping and cracklings in my speakers and the amp would turn off and on. I immediately assumed amp issues and replaced the amp with another I had. Problem persists. I check all my connections and re ground the amp to be sure. Change my signal rca what the heck. Problem persists. Just bought a new headunit thinking maybe I got a lemon it was cheap ok and if I adjusted the volume when the crackling was happening it would stop for a short period. Problem persists. I have done everything I know to do. I’m thinking maybe my remote wire is an issue considering the amp randomly turns off and on. Could a bad remote wire cause crackling? I’m at my wits end with this thing please if anyone can think of anything I have missed I would genuinely appreciate it.
