    Help me out here real quick. I'm swapping out speakers and took a "before" picture so I know where to put everything back. I noticed the wire connecting the two speakers to each other are white-negative, black-positive. However, it looks like the wire connecting the speaker to the amp is black negative, white-positive. This is the before picture, mind you so this isn't my error, but what should I make of this? The tech who worked on it most recently made the new wiring harness you see pictures. Is it possible that he just switched them in the connector vs. the wire connecting the speakers? Should I assume that is how it's supposed to be? What happens if it's wrong?

    first would be to call the tech and ask since that is who did the wiring. second, you may want to check the speaker with a 1 1/2volt battery to see which way the speaker moves. first is much more important tho. normally the black goes to negative but don't assume that.

    play music!

    I've called this tech with questions several times and he has yet to call me back, hence why I'm trying to figure it out on my own…

    What's this battery technique?

    If negative on one speaker is connected to negative on the other speaker, the color of the wire won't matter and the battery test will show both speakers moving in (or out) the same way when you connect the battery. However my opinion is the prior wiring is a sloppy job and invites a mistake for a speaker repair or replacement.

    I suppose my concern is more the wire that connects the speaker to the speaker jack being of correct polarity, right?

    I opened up the jack. Looks like the white is wired to positive.

    Your main concern is total load presented to the transformer.
    Gives me a headache to look
    Are the two speakers in series or parallel?

    So, it looked to me like the white wire on the connector is positive and the black is ground. So I switched the wires connecting the speakers to one another so that the white wire connected the two positive terminals, and the black connects the two negative. Further confusion is abated, and I already like the "new" speakers better. They were actually the originals, but the previous owner had ragin cajuns in there, which as it turns out I don't like.

    So I think problem solved. Thanks!
