    I was wanting to connect a subwoofer to my amplifier (Yamaha AX-396) but it does not have a deicated subwoofer pre out, i also biwire my speakers to the amplifier so i am confused on how i would connect a subwoofer to the amp via speaker wire?

    One other thing i should note is that on the back of the amplifier i have a L R jack labeled OUT (REC), obviously this ouputs a signal and was wondering if i could connect it up to a subwoofer that way.

    Thanks

    Greg

    Do you have this subwoofer yet?
    Most subwoofers will accept high level speaker connections so connecting your amp would not be a problem.
    Failing that as long as the subwoofer as a crossover you use the rec out.
    Saying all that my sub as neither :eek: :D .

    I think your options are
    - forego the bi-wiring
    - get a different amp
    - forget the sub

    ...unless someone can advise that you can stuff the sub and main speakers into a single set of high level outs...PJ :)

    With many subs you can indeed use both sets of wires from a single set of binding posts.

    I'd suggest you remove one cable from each speaker. Switch off your amp first of course just in case you cause a short.

    Now link the biwiring terminals on your speakers with the supplied links or some speaker cable core. It is considered a good idea to strip back your speaker cables just far enough to pass through both sets of terminals (treble and bass) rather than use the supplied linking bars. Experiment to see if you notice any difference.

    Now use the free speaker cables for stereo connections to your subwoofer's high level input terminals. In stereo L & R and maintaining correct phase.

    It's what I did. It makes life so easy and biwiring doesn't improve anything anyway.

    An alternative, if you are determined to retain your biwiring, is to take a new length of speaker cable from the bass terminals on the back of each speaker to your subwoofer input terminals. Again maintaining stereo and phase.

    Watch out for stray strands shorting between + & - terminals while you are messing about behind your speakers.

    You don't even need to touch your amplifier speaker output terminals. Because they cables are already in place from the biwiring connections at the amp.
