On the BR and BL, which wires are the positive and the negative? Are the orange ones the same and are the blue ones the same? Thanks

I don't have a service manual but if you have a 9V battery I can help.

Take the battery and tap it to the two wires. When you put battery positive to the speaker positive and the negative of the battery to the negative of the speaker the woofer cone will pop OUTWARD. If you get them backwards you'll have teh speaker pop INWARD.

Orange is negative, Blue is positive, both sides.
