i have an old am i have a red, white, purple and brown wire coming out of it.. i dont know which wire is the ground wire so i think i'm frying speaker because they're both connected to positives, because it works for abit and then you can even smell it cook is that possible? or would the speaker not work if it wasnt grounded...
anyone know what wire the ground wire is and if there isnt one, how do i ground them?
