Okay, so I want to run my bass out of two cabs, ideally using one as a sort of preamp... The cabs are matching acoustic 810's (4 ohms each). The one head is 160 watts an can output either 2 or 4 ohms ( it also has a preamp out on it), and the other head is an acoustic b600H (600 watts, matches the cab). anybody have any suggestions on the best way to rig these pizzas together? thanks for the help!
