There is no way to do this in a controlled manner without re-mastering the disc, an unrealistic option.

However, there is a very simple way to extract the out-of-phase portion of a stereo recording, which can yield a quasi-surround sound effect.

To get this effect, connect an additional rear speaker to the positive ( + ) connection of the right speaker output and the negative ( - ) connection of the left speaker output.

Please keep in mind that this only works with a stereophonic (not mono) source and is fairly subtle.

Make sure the speaker you use is at least 8 ohms.

This is an old trick that pre-dates surround sound and works with music CD's too.

This set-up will probably degrade the sound of a true Surround-Sound recording so consider wiring a simple switch to disconnect the additional rear speaker when not in use.

Hope this helps.
