I am installing my system into my car with factory stereo being used. I will be using an rca converter to make this possible. My question is should I run speaker wire from the speakers or just regular electrical wire? Using the rear "woofers" as source. Any help would be great.
none, the rca converter has nothing to do with it unless your running an amp to the internal speakers, if so run speaker wire from amp to behind the radio into the factory speaker leads.
