Polarity issue

Hello all, I changed spade connections recently on a pair of anti cable spkr wires(Paul Speltz)and neglected to mark the plus and minus sides for the amp. The spades in question are not marked so I need a way to keep the polarity in sync. I have a radio shack meter and if anyone could assist me on what to do I would be most thankful. I have the wires twisted as recomended and most of the wire is inside my spkr posts for looks so tracing them from the spkr side is not an option. Thanks in advance and enjoy the music.

i am no electrical expert, but i would think that you could place an ohm meter across the ends. if they are ends of the same wire, then there would be essentially no resistance; if you had one end of each wire, then the resistance will be infinite.

Your meter should be equipped to test continuity. Touch a spade at one end of the anticable with the black lead and a spade at the other end of of the anti cabel with the red lead. If it beeps, you have it, if it is silent, try the other spade.

Set your meter to read resistance, and use the lowest setting at that.

Touch one of the ends of the speaker cables (speaker side) with one of the probes from the meter, and then make contact with the opposite end (amp side) of the speaker cable (one at a time, obviously) with the second probe. When the meter needle (or display, if digital) reads "0" then you have isolated a single wire. Mark accordingly.
