14 Gauge, 4-Conductor, Behind-the-Wall Speaker Cable

When your setup requires installing your cable behind a wall or ceiling, this is the best cable to use in order to stay within USA building codes.  It is made of 99.99% Oxygen-free copper and includes a layer of foil shielding to prevent unwanted interference and hum induced by surrounding electrical wires.

The CL3-rated outer-jacket is UL listed and meets all building codes in the USA for fire retardancy.  It does not include the CSA mark and therefore may not pass inspection in Canada.

4-conductors are most often used to send an amplified stereo signal to two speakers which are in close proximity to one another or to a stereo volume control.
