With this you can play music from your iPod or mp3 player on your TV or amplifier! It is extremely easy to make and it is also a very cheap project. You plug the 3.5 mm audio plug into your iPod or mp3 player and you plug the 2 RCA plugs into your TV or amp. If you have any questions then post it in the comments.

Step 1: Supplies

To make this cord all you need is:

Two RCA cables (These are the yellow, white, and red cables. You can get these for under $2.)
3.5 mm Audio Plug (This it the plug on the end of your headphones. You can cut it off a pair of ear buds or headphones. You can also buy one at radio shack)
Solder and soldering iron (Optional, If you don't have one then you can use tape to connect the wires).
Electrical tape
Scissors or wire strippers

Step 2: Making It

Follow the circuit diagram to make it. If you are using a 3.5 mm audio plug from a pair of headphones then there are four wires coming from it. Two are grounds for each of the RCA plugs and one is the right channel and one is the left channel. For my headphones the right and left channels were in green and white insulation while the two grounds were bare copper wires.
 

Now it is time to plug it in and listen to your music!

    Hey if I were to use this setup for a subwoofer, would I just connect the right & left channel together? since 1 sub is mono.

    Sadley no because you would need to connect your music source to an amplifier and then connect your amplifier to your speaker otherwise it won't work from the music source to the speaker alone.

    an amplifier with a power source is needed in the middle or after the audio but before the speakers.

    I made it! Simply stripped a headphone wire and the red and whites from an old Playstation, connected the reds and the whites and the grounds. Plugged the red & whites into the rear of the stereo, and there it is.

    Will this work if I use dual headphone plugs instead of RCA plugs? I need to connect a one cable for headphones & mic to a PC which uses two separate cords for sound and microphones.

    Thanks for the great instructable . If you have the right stores near you, you can buy this setup quite cheap.

    I've been able to buy this setup ready-made at Radio Shack for many years. I have radios, boomboxes , amplifiers in various rooms in the house with one of these cords attached, for super sound. You can buy cheap boomboxes on eBay - you have to type "aux in" when you search, so you have a place to plug it in. Same for great sounding keyboards.
