RCA Wire Leads are the protected cables, which are used to convey line level signals, which are non-amplified and weak signals. These have metal plugs on all end and are often color-coded. They are utilized to connect the audio output of all of the audio inputs. These are also utilized to make connection to the subwoofer and allow for advanced utility. RCA Wire Leads are offered with a frequency of 50/60 H2 Hertz (HZ). These work as the electrical connectors, which are needed to carry both audio as well as video signals.
