An RCA cable is also used to connect a subwoofer or an LFE (Low Frequency Effects) output to the subwoofer. Speaker cables, on the other hand, are used exclusively to connect the subwoofer speakers . Speaker cables can also be used to connect a passive subwoofer that cannot amplify the signal from a line-level RCA input.
Save your RCAs, speaker cables are cheap. I’m pretty sure yes, you can cut off the RCA plug ends. I would leave about 12 inches of cable on that end just in case you want to use the RCA connectors then you could connect the new cable to that.
Our Cmple Audio Coupler is used to connect two stereo audio cables with RCA connectors for longer length. This handy jack coupling ensures a reliable and precise connection with corrosion-resistant, nickel-plated plugs.
Splicing your speaker cables can be an incredibly effective way to increase the length of your cable runs. If done well, you really shouldn’t notice a difference in your audio playback. However, if done poorly, it can cause audio dropouts and even short circuits.
Need audio? Use the VGA video cable. What connections are on the back? Red/White/Yellow RCA S-Video White/Yellow RCA (This is mono audio. You can use the RCA cable, but don’t connect the red one.)
RCA cables are coaxial cables, which means that each cable has a positive conductor (inside) and a negative conductor (outside). The two different cables are the left and right stereo audio channels.
A basic RCA cable has three color-coded plugs that extend from one end and connect to three correspondingly colored jacks on the back of a TV, projector, or other output device. It transmits audio and video signals from the component device to the output device (e.g. TV or speakers).
