    Hi there,
    I have a 7.1 amp and I have them driving 5 speakers right now (2 Full range front, 2 surround and a center). Is there any way I can leverage the 2 unused amp out to biwire my fronts and get some extra juice out of them.

    Thanks,
    Nishant

    Sure can...if, your speakers are bi-wireable and if your receiver allows for setting the rear two channels for bi-amping.

    Don't know exactly what that means (an amp doesn't know which channel is which, it just amplifies), but if you can bi-amp your speakers, you would run a splitter to 4 amp channels and bi-amp the mains. This should be a slight improvement in power, but will likely not be a night and day difference. If you can bridge two of the channels, you might get a bigger improvement.

    What speakers and what amp?

    I've seen some receivers that have 7 amps and an A and B main speaker setting, and the B speakers can only be driven if the surround back channels are not set up (as in a 5.1). in which case Nishant can use the B speaker output to bi-amp. I agree that it might not be a night and day difference though

    He said amp, so I didn't want to assume he meant receiver, though that IS probably what he meant. If this is a receiver, you won't be squeezing anything extra out of the receiver by doing this (and you won't be likely to be able to bridge channels either).

    If it's a receiver, the process varies with the model.

    Here's a a discussion of how to biamp the Denon 3804 for instance.

    Disclaimer: I own a considerably less capable setup-- I only came across this article while doing product research. Needless to say, it is not bi-amped.
