    I'm rewiring and re-speakering a 2x12 cab. On a jack like the one in the picture, is the + lug the one attached to the center metal part and the - lug the outer one? Or vice versa? 20210301_100610.jpg

    Yes, the tip of the plug is positive

    The + normally does NOT go to the center metal part.

    Bigben, the tip is the ‘positive’ on the plug. You can follow the contacts by looking at the Jack from the side. That center is ‘ground’ and contacts the sleeve of the plug.

    The other part of the equation is which pole on the speaker is positive. Ex: vintage Jensen’s are backwards from most other speakers.

    Thanks. I wired two 8 ohm speakers in series to 16 ohms using this diagram. I just wanted to double check before I buttoned it all back up. Im confident I did it right. Screenshot_20210301-103731_Gallery.jpg
