With the Amps just plugged into the speakers the hum is still there
Is the preamp disconnected or just turned off? If off disconnect the preamp at the amp end. Also is the hum coming out of both speakers? Does the hum occur all the time? Which amps do you have? Some amps are known to have a low level hum.
