Picture of Audio/Video Cable ( RCA Connector ) Splicer/Splitter from Salvage

Sometimes your cables are too short so you want to join the two cables to make a longer cable, you need a splicer or coupler.  Sometimes you want to split the cable  ( for example to feed 2 amplifiers the same signals ) then you need a splitter.  RCA connectors are commonly used for both audio and video signals ( see picture ), so here we will make couplers and splitters for RCA cables.
