    NO! Not if you want to keep the magic smoke inside your amplifiers!

    ?

    What felix described above will work fine. Just daisy chain the amps with the loop output and remove the jumpers from the binding posts of the speakers. Hook up one amp to the bottom set of binding posts on both speakers, and the other amp to the top set of binding posts on both speakers.

    Another way of utilizing both of those amps would be to run them in mono, with one amp per speaker. If you do this, then you'll need to leave the jumpers on the speakers in place, and the amps wouldn't be daisy chained.

    Try both ways. I've heard that they don't sound as good in mono, but I have no first hand with those amps. Experiment and see what you like better.

    Also, if you're running them in mono, refer to your owner's manual about which line-level input and which speaker terminals on the amps to use.

    Falcon is of course correct that if bi-amping, and you get the sections seperated, it's all good. The way the question was posed, I thought it best to stay on the first level and stop the possibility of hooking both amps to the same point!! I had visions of wires being tightened down at that moment....

    Also...welcome to CP!!

    thanks guys but will this work to if i put the left input on both amps to one speaker and the right input to the right speaker since they are 2 channel amps will that increase the power going into the speaks

    See my post above that describes how to do this. It's called "bi-amping"

    "Just daisy chain the amps with the loop output and remove the jumpers from the binding posts of the speakers. Hook up one amp to the bottom set of binding posts on both speakers, and the other amp to the top set of binding posts on both speakers."

    On second thought, let me be more specific, just in case...:smile:

    How to hook up the RCA's:

    Run you preamp's Left and Right RCA outputs to the normal Left and Right RCA inputs on Amp #1. Then run another set of RCA's from the Left and Right Tape Loop Outputs of Amp #1 to the normal Left and Right RCA inputs of Amp # 2. (this is called daisy chaining; you could keep this chain goin to any number of those amps)

    How to hook up the speaker cables:

    *MAKE SURE THE JUMPERS ARE REMOVED FROM THE SPEAKER'S BINDING POSTS*

    Amp #1:

    Run speaker cable from the Left speaker terminal of the amp to the TOP set of binding posts on the LEFT speaker. Run speaker cable from the Right speaker terminal on the amp to the TOP set of binding posts on the RIGHT speaker.

    Amp #2:

    Run speaker cable from the Left speaker terminal of the amp to the BOTTOM set of binding posts on the LEFT speaker. Run speaker cable from the Right speaker terminal on the amp to the BOTTOM set of binding posts on the RIGHT speaker.


    Here's a link to your owner's manual if you don't have one:

    Good luck! Let us know how it works out!:biggrin:

    Not really, but thats ok, it's about as close as we get around here these days.:tongue:

    I would avoid running them in mono, they may not like less than an 8 ohm load bridged. You could just get a splitter too and run one amp for each speaker without having to run them mono. The top half of that speaker uses very little power.

    The method tonyb describes is vertical biamping, whereas the method I described is horizontal biamping.

    tonyb's method has the advantage of not having a single amplifier power the power-hungry low sections of both speakers, which is probably especially useful on your particular speakers, seeing as the low sections require much more power than the high sections.

    Neither is considered true biamping by some, because in true biamping you'd use an external crossover between the preamp and amp and then bipass the crossovers in the speakers. I'm pretty sure about this, not positive. I am right? Anyone? Bueller?

    Yeppers....,either way is cool, won't make a bean of difference imho which way he chooses anyway. I would just avoid using them in bridged mode is all. Other than that, rock on.

    I will second the motion to not use them in bridged mode.
