    k I have 2 lines coming from my crossover, one for the
    highs and one for the lows. Do I just run these to channels
    1 and 2 of my power amp as if they were left and right
    strereo? then just run the respective cabs off the each
    channel, ie run my lows to channel 2 then plug my 15" cab
    to channel 2 output. And If I'm using 2 8ohm cabs will the amp be pushing at 4 or 8 ohms in stereo mode? Also what brand makes the best
    poweramps for bass?
  2. That is exactly correct assuming your amp is operating in stereo mode (as opposed to bridge mode). One channel for each crossover output. An 8 ohm cab will will draw the 8 ohm rated wattage for that particluar channel. As for best power amps for bass, you can't go wrong with QSC but there are many other good ones as well.

    Yeah, what they said.

    One thing, though.....if one channel has enough power for your lows, then a lot of the other channel's power goes unused. You could get louder or cleaner by using that power on lows, but you don't get the chance.

    I have usually found that going bridge mono full range, if you can, often overcomes with power the problems that biamping is intended to fix.

    But if the speaker doesn't have a crossover, you are stuck biamping.
