I currently have the base 4 speaker system and looking add the 3 1/2" dash speakers. Does anyone know if they are pre wired and just need speakers installed or do I need to pull all new wires? Also are their wire outputs from the the stock deck or will the need to be wired to the front door speakers?

Thanks

My 02 has the base model speaker package and it does not have the wires in place.
