the one going through the cap should be the Positive lead.

which is + and which is - on the speaker? i would take a short piece of speaker wire and attach it to the speaker. then just use a cordless drill battery or something of that sort and just hold the wire to the batterys + and -. if the speaker moves out then in (it will make a pop) sound, then you have it right, if it moves in then out, then it is reversed.
