Can the wires in the back of the unit cause a whinning noise if to close to the hu?

shouldnt cause a whining noise. are you using aftermarket amps? what vehicle is this in?

04 yukon, no bose and no onstar, i was gtting a whinning noise so i took the dash off and moved some of the wires and rca plugs away from the hu, now i get no whinning noise.

sounds like an intermitent short but as long as its not doing it now your good to go.

yea that whining was not load but it was load enogh to get on my nervs lol

make sure the wires have good insulation around the connectors. use electrical tape liberally or shrink wrap over the solder joints. wire strands could be touching making noises.
