Do RCA cables work for subwoofers?

Similarly one may ask, do RCA cables make a difference?

Only if they're broken, or unusually susceptible to noise.Cables can do nothing to "increase" sound quality,but in some rare cases they can be designed so poorly that theypick up noise, or make poor connections.

One may also ask, what cable do I need to connect subwoofer to receiver? If the subwoofer's 'Line In' uses RCAcables (and if the subwoofer out on thereceiver/amplifier also uses RCA), simply plug using an RCAcable and choose either the R or L port on thesubwoofer. If the cable is split on one end (ay-cable for both right and left channels), then plug inboth.

Also asked, do RCA cables carry power?

A simple RCA cable has three color-coded plugsextending from one end of a cable that connects to threecorrespondingly colored jacks on the back of a TV, projector, oranother output device. These cables carry audio and videosignals from the component device to the output device (i.e. atelevision or speakers).

Is a coaxial cable the same as a RCA cable?

A digital coaxial connector looks like anRCA connector, but it transmits digital data instead ofanalog signals. The digital coaxial cable is thicker than atypical audio cable, however, because it uses thesame type of shielded coaxial cable you use toconnect your television to your cable box.
