Steve.......I would convert the amplifiers to 240 volts if it is just an internal jumper configuration and then feed each of the amplifiers with a 2-pole 30 amp breaker and 30 amp 240 volt wall receptacles. You will need to install a minimum of #10 average wire gauge copper wire for the 30 amp circuits to each amp.
