Right, so lets go hypothetical.
My hifi has a L + R output. L has a + and - and right has a + and - on it.
On the speaker, there are 2x + and 2x -
All I have is 4 length's of speaker cable (two lots of twin cable)
What do I connect to what? Do I connect one end to the + and - of the Left output and the other end to the two metal plates on the back of the speaker or what?
