What Does RCA Stand For?

RCA stands for Radio Corporation of America. It is an electronics company that originated in 1919. RCA cords continue to be an integral component for enhancing sound quality in-car stereo systems, home stereo systems, home or public theaters, and more. 

Uses of an RCA Cable

RCA cables carry video and/or audio signals depending on the type of device you are hooking up. You might use them for:

  • Gaming systems
  • Televisions
  • Car stereos
  • Public or home theaters
  • DVD players

Whether it’s a gaming system or DVD player, you will have to hook up an RCA cable to enjoy it. Sometimes there will be an HDMI cable instead of an RCA cable like on some higher quality game systems.

For example, a PS1 has RCA cables while a PS4 has an HDMI hook-up because it’s a more updated model. HDMI helps to improve 3D support and enhanced audio quality. 

How to Use an RCA Cable?

Use an RCA cable by following these steps:

  • Match the colors of the cords with the color plugs on your device
  • Put a yellow cord in the yellow slot
  • Place the red cord in the red slot
  • Install the white cord into the white slot
  • Reassure your device connects to a power source
  • Power up your device and enjoy

If you already have the RCA cable that you want, look for an RCA extension cable to expand its length if needed. 

FAQs About the Best RCA Cable for Car Audio

When you are looking for the best RCA cable for your car’s audio, you may still have some questions during the buying process. Here are some frequently asked questions about car audio RCA cables. 

Can you use regular RCA cables for car audio?

A standard RCA cable is permissible to use for car audio. However, subwoofers can use RCA cables as well. A subwoofer RCA cable will enhance the sound’s overall quality because of its enhanced thickness versus a standard one. 

Do cheap RCA cables affect sound quality?

RCA cables do not increase or decrease sound quality. However, if a cheap RCA cable is poorly constructed, it could pick up unforeseen noise. A cheaper RCA cable will also not stay connected as well as a higher quality one will. 

Does the color of RCA matter?

Yes, the color RCA cable should match the corresponding color input. Red stands for the right audio channel. Yellow is the composite video of the device in which the cables connect. The white cord (or black) stands for the left channel of stereo audio. 

Are gold-plated RCA cables better?

Gold-plated RCA cables are a higher quality alternative to standard RCA cables. Silver or copper are conductors, which are better than the usual conductors used on standard RCA cables. Thicker conductors carry the connection between the wiring and the car audio better. 

Does RCA cable length affect sound quality?

Cable length does affect an RCA cable’s sound quality. A longer RCA cable usually means more enhanced quality. 

Do the RCA cables for your amplifier increase voltage as the head unit volume increases?
