On an RCA plug--for coverting a speaker/or seperated connection that has positive and negative on it--which part is negative and which part is positive?

Are you just trying to Connect RCA wires to the speaker wires?

If so it won't work you need the Converter box to do it.

I'm calling shanaigans Tech....you can wire up speaker wires to an RCA plug (for the record, the midle "plug" on an RCA jack is negative) I've done it where i had a couple 6x9's plugged into the rear RCA output on a pioneer. There wasn't really much a difference though.

The Sound Quality Is really Poor and It could Blow the speakers from having it hooked up like that.

RCA's work on a Low Level Speaker wires run on a High level output.
