RCA-WH.Y1/2 is part of the Carmedia series of connectors, which are designed to provide an easy method of connecting audio components in a car’s entertainment system. They are two-pin connectors and each pin is color-coded white and yellow. The male and female connectors are symmetrical, meaning that the yellow-coded pin draws the audio signal, while the white-coded pin provides a ground connection. The connectors are used to link audio sources, such as a head unit, multiple amplifiers, and speakers, as well as other add-ons such as equalizers and processors. The RCA-WH.Y1/2 system reduces the amount of wiring and complexity involved when linking components together, by providing a single, efficient connection point.
