On the stock speaker wiring, there'* one tied wire, and one without a knot in it. Is this stock? Which is which? I need it because I'm going to have one aftermarket speaker from now on. Please let me know.

In the factory setup. Two wires run to a connector w/o knotting or twisting.

That'* terrible. I guess some installer at a retail chain did that. It will not be hard at all to ohm out the wires, or I could just hook up either one, and then when I plug them into the amp, the wires that work I'll keep. Or I could be ÜBER HARDCORE RADOMIR and run all new front door speaker wires since the stock ones are thin. How hard is it to break out the speaker wires from under the dashboard?
