Which is the + wire?

[alex73013]

I cut my speaker cable and attached crimps to it so I can use an attenuator for my combo. Which is the positive wire?

id assume the red wire goes to the tip of the jack but you can test that with a meter. i always test these things with an old 9v battery, like 5v instead of 9v, ive heard you can hurt your speaker with a strong 9v but it hasnt ever happened in my case. i want the + on the contact that makes it play forward. attach the spade connectors to the speaker and see which way the + battery terminal makes the speaker move forward. its easiest to tell by having a hand touching the cone lightly

Looks like the red since it is going to the center, the - is probably connected to the outside shell, so you could check that with an ohmmeter.
