hi,
i went to hook up my speakers today but after connecting the door speakers my head unit tells me there's a wiring problem. i took the passenger speaker out and set it on the floor and it worked but as soon as i put the screws in, that error message comes up again and won't play music. i think it has something to do with a bad ground. i tried using rubber washers on each side of the speaker, as well as wrapping the screw with electrical tape. same problem. what can i do to fix this?
thanks.
