what type of wires did youuse for the install? I would recommend using shielded wires with shields properly grounded at one end (if you ground at two ends, you may create a difference in potentials between the ends of wire, defeating the idea of grounding). In this particular case, you may have the sound wires lay alongside power wires, or maybe even criss-crossing them - your wires are picking up some induction... To eliminate it, you might want to wrap each sound wire in metal (aluminum) tape, and then wrap the wrapped wire in insulating material, to avoid the exposed metal jacket to short something somewhere... thus, effectively creating a shielded wire, but rather with a home-grown solution...
one other option is to use magnetic rubberized sheets, cut in long slices, and use them to wrap... all of the above is ugly for sure...
or..
i may suggest using Belden 9451 SB cable for this purpose... or similar...
