I have an Ampeg B4 amp that I run through an Ampeg 8x10 cab. The back of the amp says that it puts out 1000 watts if it is monobridged. That sounds pretty good, but what would the difference be if I run each channel (500 watts per channel) into a seperate input on the cab? I have tried it, but I don't hear any difference. It may be that I only tried it in our rehearsal space, which isn't the best place to work on good sounds.
