    I did a search. I'm OCD. Just to verify: when wiring speakers, black is (-) and white is (+), correct?

    With that colour combination, yes!
    You won't break anything wiring it wrong though, but it might soun "thin"!

    One speaker in an amp cab? won't matter. It's AC voltage anyway.

    Only time it matters is when there are more than one speaker playing the same signal.

    Then as @The_Nuge said above, phase becomes an issue and one speaker wired backwards will make it sound thin without much bass.

    Normally you want the speaker cones to move in the same direction when hit with a voltage.

    Speakers are polarized just so you can match them to all work together.

    Put a 9 volt battery across the terminals briefly with the battery positive to speaker positive and notice the cone moves outward.

    Switch the battery polarity and apply the negative battery post to the speaker positive terminal, and the cone will pull inward.

    What happens when they are wired backward isn't dangerous to the amp or speaker, it just results in one speaker cone pushing out on a given signal while the other one is pulling inward at the same time.

    Equal and opposite reactions dictate that the pressure wave created by the outward moving cone, will be swallowed in the vacuum created by the inward moving cone next to it.

    That's all......
