I would just connect them up and if you don't like how they sound one way try the other. |

turn the radio on and hook up the meter. note what wire u touched to the speaker wire if you get a reading then that wire is the hot one. if you get a reading with a - sign next to it the they are oposite. |

hook up a speaker and play a test tone of say below 100 Hz and see if the speaker is moving outwards, if so it is wired correctly. If it is moving inwards, it is wired incorectly.

Ya the test tone at 100 Hz is a good idea, that should work. When I connected the meter to the two leads i got the same readings. Proably because AC has an alternating current flow. |
