What is RCA on a car stereo?
RCA and HDMI are two different ways of sending audio and video signals. HDMI is a digital connection for transmitting video and audio through a single cable, while RCA connections are mainly used for stereo analog audio or analog video signals. Although RCA is also used for a coaxial digital audio connection.
Do RCA cables make a difference in car audio?
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 they pick up noise, or make poor connections.
Is RCA good sound quality?
It’s pretty safe to say that RCAs are in limited use for the average home user, mainly because of market shifts. However, RCA audio quality is still phenomenal. If you still have a device that uses this connection, hook it up and see for yourself!
