It could be oscillating. Cat5 spkr cable normally has pretty high capacitance.

the sound hasnt been affected, if the twists of the wires were wrong (followed the twisted pair instructions off tnt) could this cause this type of problem, if it is oscillating what can be done?

Go back to your previous speaker cables

. You said yourself the sound has not been affected...

Otherwise, look into a zobel network (here or audioasylum cable forum). I'm not much of a believer in cable, other than sound construction at a reasonable cost, so you can take what I say with whatever grain of salt you wish.
