How To Pick The Best RCA Cable For Car Audio?

There are a few things you have to look out for when choosing a new RCA cable. We wrote them down to help you pick the best cord.

Price

This might not seem important on a technical level, and it honestly isn’t. But it is worth noting you can get a worthy cable for your price range. Choose the one you can afford, not the one that cost more (quality isn’t always dependent on the price).

Quality

Now technically speaking, this is the most important thing to watch out for. Once you have a price range focus on the quality, go through the comments, and use others people’s experiences to form a rough idea of which cable has the edge above the other.

Specs

The last important, but not the least important thing to take note of is the specs. Is the cable you chose the one that can do what you need it to do. Check the specs and see, and if you don’t know enough about it there are plenty of places to learn from.

How to Use RCA Cable in your Car?

Use the RCA cord 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 cable that you want, look for an RCA extension cable to expand its length if needed.
