Just purchased the soundtouch 300 soundbar with the rear "wireless" invisible speakers. The wireless speakers however come with a huge power adapter wich I cant hide anywhere. The plan is to hide the power adapter near my tv and that the cable between the speaker and power adapter goes around the walls. The problem is that the cable is 20ft and is 5ft short.
Is it possible to extend this cable so that I can hide the adapter near my tv? If its possible what kind of cable do I need, thickness, quality etc..? Are there any other requirements?
