Selecting wiring for your home theater wiring is important as it affects the speakers' performance, and will impact the ability of your speakers and amplifier to deliver high-caliber home theater sound. Ensure also that your speaker wire support the power rating of your sound system, and avoid speaker wire thinner than 18 gauge. Thicker home theater wiring is more expensive, but it produces superior sound.

Be sure to position your speakers in positions that optimize your sound and consider your listening position and the room’s acoustic properties before you run the wire. Pre-wiring your home for home theater/surround-sound during remodel or new home construction offers the best return on investment, as no wires will be visible.
