    Default 4 wires to each speaker

    I have 4 wires going to each speaker. My old speakers have a red/white on the positive terminal and a green/black on the neg. terminal. New Polk speakers have 2 Neg. and 2 Pos. posts. With the jumbers on, can the wires be split with one each going to the each of the 4 posts?

    take the jumpers off your polk speakers (just unscrew the post) and run them the same way your old speakers were run. (positive red and white - negative green and black)

    On the amp end of things, twist the red and white wires togethers and plug into the positive terminal. Twist the Green black ends together and plug into the negative terminal.

    This is the classic definition of bi-wiring a speaker. If you have multiple amp outputs you can add that into the mix, but unless you say you have it available, I don't want to confuse this discussion with it.

    Welcome to the Forums.

    In a word, no.

    If you wish to biwire by using all four posts, you must remove the jumpers. The jumpers are in place for the purpose of using only one pair of posts.

    Thanks for the quick response. The poblems is that the wires when twisted togeter will not fit into the hole in the post. What is the effect of leaving on the jumper and running one wire to each terminal?

    Sorry, but this is my first time on this forum and not sure if I responded correctly. Apologize if this is a repeat.

    What is the effect of leaving the jumbers on and connecting one wire to each positive and one wire to ech negative?

    When twisted together, the wires will not go through the holes in the terminal.

    You can run one set of wires if you choose to and be done with it. (keep the jumper in place)

    To bi-wire:
    Run one wire to each terminal on the speaker and at the amp end get a pair of bannana plugs and twist the wires into the banana plugs. Then you can just plug the banana plugs into your amp or reciever.

    If you wire all the posts and leave the jumpers on the result is your speakers will work. Be sure the posts with the positive wires on the speakers are hooked to the positive post on the amp/receiver and negative to negative. However, as you were told nobody does this, they remove the jumpers, which you should do if you are wiring all the posts on the speaker.

    Not sure if your question was answered for you, but I'll add my 2 cents, and I have a question.

    You seem to be asking 'attach 1 wire to each of the 4 posts on the speaker, but don't tie them together on the amp end'. Is this correct?

    If so, where are you hooking them up to on the amp? I'm assuming you have only 1 set of "fronts" on the amp. If you are hooking each set of those wires to different outputs, don't. That may not be a good thing for your speakers (or you amp).

    As an FYI, the purpose of the 4 posts on the speaker is to allow seperate wiring to the tweeter and woofers. The purpose of this is to allow a better signal to be sent at each of the frequency ranges. So if you can (or want), hook up a set of wires to the top, one to the bottom, tie them together at the amp side (pos+pos, neg+neg) and attach to the post. There are a million threads in here on bi-wiring, with the goods, the bads, the whys, the why-nots, the hows, the whens............(I haven't bi-wired yet, but it stirs up a bit a conversation when the question comes up, and eventually someone refers you to an older thread).

    Hope this helps a bit.
