I'm looking at getting some better cables to run from the AudioByte amp to the speakers (L,R,Sub) to see if it helps supress some low frequence Hum I get on the Sub. I'm a bit confused as the current ones are 3.5mm Stereo leads to each speakers but I would have presumed they would be 3.5mm Mono. Can anyone confirm what is needed.
