    quick question. on speakers, does the positive wire always go on the left and the negative on the right? I have Definitive Tech BP2002 and in the book it shows the positive/left and negative/right but on the speaker itself the black caps are on the left and the red on the right. Is there any way i can tell for sure which is positive and negative?

    Take a 1.5v battery and connect the + of the cell to red of the speaker and the - of the cell to black of the speaker. If the woofer moves out then red is positive, if it moves inward, then red is negative.

    Normally red is always positive, no matter where it is physically.

    Aaron,

    John is right: The universal standard is red = (+) and black = (-). Position is irrelevant (many receivers have vertical speaker connections!).
