    USA S.U.B. Passive Wiring

    Hey
    So I just recently got a passive USA sub and one of the pots is not wired in.

    Would anybody be able send a picture of their passive setup? Or be able to direct me to a wiring diagram?
    I msgd customer support but was hoping to get some quicker answers here.
    Thanks

    In passive circuits pots just bleed/siphon off signal to ground. If it’s a tone pot it does so thru a capacitor.

    Iím not sure what that means for me. I feel like your saying just wire it in like normal..
    But Iíve only soldered like 4-5 other pots and If im not looking at something or told step by step Iím helpless.
    There is a capacitor already soldered to the pot but thatís it, no other wires connected to it and Idk which ones to connect where.

    Has a cap so itís a tone pot. Should have a lead heading for a ground. Not all that rare for ground lead to somehow fail.

    That much you can check visually without any pictures to guide you. If that doesnít solve it then youíll need a picture and passive subs are rare. If you canít get a sub photo you might find a photo for a passive P-Bass. Most single PU circuits are more or less alike.
