Easy-to-follow instructions for creating RCA cables

RCA cables are used for many audio applications. If you want to install custom audio systems in your car or home, making your own RCA cables ensures that you have a clean system with no excess cable. Making your own cables can save you money, as well.

Steps

  1. 1
    Turn on a soldering iron. Do this first so it is hot enough when you begin soldering. Make sure the tip of the iron is not touching anything, and that it is safely out of the way so you do not accidentally bump into it.
  2. 2
    Cut an audio cable to the length you need.

  3. 3
    Remove 3/4 inches (2 cm) of the audio cable's outer jacket.
  4. 4
    Strip the conductor wires. Many cables have 4 conductors. If this is the case, just twist the common colors together.
  5. 5
  6. 6
    Apply heat shrink wrap. If you plan on making multiple cables for a stereo application, use a different colored shrink wrap for the left and right channel.
  7. 7
    Disassemble your RCA ends and keep all components neatly in one place.
  8. 8
    Slide the outer barrel of the RCA ends onto the cable past the conductor wires. This is necessary in order to be able to screw the end together once you've soldered it.
  9. 9
    Connect the signal conductor to the RCA end. Find the U-shaped piece that runs in line with the center pin. Insert the tinned conductor end into the "U" and apply the soldering iron to the wire. This will heat up the solder and connect it to the center pin. If necessary, apply a small amount of solder over the top of the wire to assure a solid connection.
  10. 10
    Connect the ground connector to the RCA end. Find the long tab that extends out of the RCA end and has a hole in the center. Insert the tinned ground connector into the hole and apply the soldering iron to the conductor wire. This should be adequate enough to make a solid connection. If needed, apply a small amount of solder on top.
  11. 11
    Thread the outer barrel and the end together.
