No aftermarket radio is in my car or was. Everythings stock except for front components and an amp for that. But that has nothing to do with my sub i believe. So which line is my ground wire and is the ground wire the reason why my sub is not working? So that silver circle thing on the top of my roof of the trunk is not a ground wire?
