Hi all, I could really do with some help if poss! Apart from my big install there is another room with a Sony Home Theatre (DVD/Amp all-in-one) unit. My requirement... To put a switch in between the speaker cables of the front/rear speakers and the main unit (Amp) - When the switch is in position A then all works as normal. - When the switch is in position B then the front speakers become the rears and the rear speakers become the fronts! - it needs to be as cheap as poss too! Any ideas really really appreciated. Thanks, Mark.
