Double Bass Acoustic Image wiring URGENT!

[obcorm]

Just put in a new speaker into a series 2 contra and don't know which wire is which. Rookie mistake! need to use the amp in a couple of hours so if any can help me out I'd really appreciate it.
Just need to know which is + and -

What colour(s) are they?

Black is typically the minus with red being the positive. It matters with regard to the relative phase of the other drivers. I hope the driver you installed is the same as the original.

Black and Red, drurb, that worked, thanks. Driver is direct replacement from AI. Old one died on me. Thanks guys.
