the speaker wire with only red and white wire only has to be connected to banana plugs with three wires i.e red,blue and a bare wire going to a subwoofer input, how do i get this connected properly with good sound?
This would be a lot easier to answer if you told us what model of speakers you are talking about and, come to think of it, the sound source. But all we would do is find the manuals online and read them - can you try that first?
