the diagram is a crappy diagram i made of my sub. well here's the problem. the connector labled as A works' it's my negative connector.
but connector B does not work. So i doubled checked it by placing the Positive wire directly onto the wire coming form the speaker. and it works that way.
So i'm thinking that the wire must not be connected well. so i decide to solder the baby!.
So i soldered it and well. that didn't work.
I need help any one know what's wrong with it? worst come to worst i could just bypass the connector B and just attach the wires directly huh. any suggestions

That's what I'd do. Solder them toghether directly with some shrink tubing. The only thing with that is if you change your setup, it's gonna be a pain to diconnect and reconnect the wire.
