Picture of RCA to 3.5 mm TRS cable

This is a custom tutorial for making your own RCA (aux cable) to TRS end (the same on on your headphone jack).

Why make this? - you can hook up your mp3 or laptop to your surround sound system.

Okay! so let's get started

Why not just buy it in store? - You are always free to do so, but in some regions it is hard to find stores that will sell these types of things, especially if you live in a less urban area. Some stores also can charge a fairly large amount of money for such an easy project. Plus this is really fun and you can feel proud you did something.

Step 1: Get a regular RCA to RCA cable

An aux cable works well too, just the yellow end should be unused since it is for video, and we're dealing with audio.

The next thing you will need is a 3.5 mm jack. I got this by trimming the end off my broken headphones with scissors.

These cables are available from the "Dollar Tree" stores (at least in the United States) for $1.

in the united kingdom, most pound/bargain shops sell these, and they are better quality than a handmade one...

Wouldn't it be more structurally sound to splice the wires from the headphone jack? or does it get more complicated?

Yes it would, but many times the color wiring are different for each headphones. In order to see which color is which, you would need to see the soldered parts, which is usually hard to see. The regular wiring colors are copper to ground, red to right and blue to left. My headphones; for example, had 4 wires and copper wire, so its sometimes can get difficult. If someone could correct me if in wrong in some parts that would be great :)

You're more knowledgeable on this than I am, planned on doing this myself with a multi-disc surround sound system I have that the disc changer went out on, you have my gratitude for taking out all the guess work, thank you! Great i'ble!

XD Thanks! I'm not that great at this myself but thanks. If your system works I want some pictures if you don't mind.
