With the amBX system, the Audio Out (Line Out) from the PC connects to the subwoofer
which contains a built-

The Audio In is a standard 7-
To make sure that you get the best sound, connect the output from the new amplifier as shown on the connections list above.
You will need to make sure that the phases are correct. If they aren’t, the speakers will work OK, but the sound may be a bit flat.
I’ve gone into details here, but it’s a much simpler job than it sounds. Basically,
all you need to do is connect the four output wires from the amplifier to a 7-
