Pardon my ignorance on the subject, but ive got a few questions on biamping heads. As far as im concerned, people biamp so that they can eq both heads seperately and/or distort one and leave the other one clean. correct me if im wrong. so how is this done? how is it wired so that the signal from the bass goes into both heads at the same time? do you need 2 seperate cabs to biamp, or can you run 2 heads into one cab that can handle the wattage?
