    This makes no sense. Try drawing what you are doing or take some pictures.

    i said before there are two wires coming out of the PA, i connect them to a single other wire and plug it into the cb... and it doesnt work, but now im getting some noise from the pa when turned on but its still not letting me talk through it, it only clicks when i push the button on the mic

    Both of those wires need to be hooked up to a separate place, think of it as a car/home stereo speaker.

    Your PA horn has a + and - wire. The + wire needs to be soldered to the center post of the mini jack, the - wire needs to be soldered to the negative terminal, usually anywhere except the center post connection.

    This will complete the circuit rather than dead short it like you currently have it. I have included a picture. This is not a mini jack (I did not have one handy), it is an RCA connector, but the terminations are the same as a mono mini jack.

    x2. I couldn't remember which wire went to which part of the post. If you plug it into the ext speaker on your CB, you can listen to the radio outside of your truck, as well.
