so i would personally bridge to channels to run the sub and use the other to channles to run the 6x9's.....but thats only if you can turn on the cross over for only one channel at a time......the cross over takes all of the high frequency sound out of the channel so it only gets bass allowing the sub to have a clearer sound and not burn out the voice coils....if when you turn the cross over on it does it for all channels then you will only want to run the sub off of that amp and bridge all channels together
