A friend of mine asked me where to get an audio jack for playing his ipod with the car speakers. Then I thought why buying one? Because you can make one out of your old earphones!!

Step 1: What You Need

1. Two pairs of old earphones
2. Soldering iron
3. Insulating tape
4. Helping hand (Optional but it's always useful to get one)

Step 2: Pair the Wires Together and Solder Them

I cut away the earphones part and left me the wire bits and 2 jacks/plugs. There were 4 wires on each pair of earphones. First of all, you should identify the similar colours and pair them up. However, I got 2 wires which were different from the other side. I paired them up anyway to see if it works. Then I soldered the wires together and test it with my ipod and speakers. IT WORKS!! Finally, wrap the wires with some insulating tape.

Step 3: Now Use It in Your Car or Home Speakers!!

Simply plug it to the 'Audio input' in your car or home speakers. For some stereo, you need to change it to 'AUX' mode.
From where I live (UK), the same audio jack cost £5.99 in a store. Now you can make one for free with your old earphones!!
Hey umm when i did this my head phone jack end has 3 wire not 4 like yours does can you help me please?
I have done this using just one speaker (as its a very old classic car) and the Ipod just isnt powerful enough and the distortion is unacceptable. I was going to look into putting in a small inline booster or something?
doe,s it work in speaker ?<br /> <br /> <br />
nice instructable, just to let you know the copper doesnt have to go wither their respective colors, its just ground and ends up in the same connector anyway<br />
this is supid. they sell these types of cords for like 1$
SWeet!!! just soldered it together and it works awseome!! thanks!!!!
I buy my 1/8" to 1/8" cables at the dollar store. The time spent making this cable is worth more to me than a dollar. Nice job, though.
ya i have more important things to work on like Sheila (my computer yes Sheila like Red V Blue)
But you forgot about the gas it took you to drive to the dollar store. Add another dollar. But now consider the time it took to drive to the dollar store. And also the risk involved in getting on the highway. And what about wear and tear to the car's engine. By the time you add up all the pros and cons it comes out about the same.. :-)
That's cool man. UK is so expensive, it cost £5.99 to get one!!
Oh wow, that's too bad. I was going to say, in the US, you can get these cables for under a dollar. (No sacrificial headphones required.) ;) But hey, if you have the parts and the time, it certainly is easy enough to do.
Hm I done exactly what it said an the sound is very quiet no matter how loud I turn it up an theres like a distortion noise thats loud, not sure why isnt isnt working properly
i believe it doesn't work? don't know if it's just me i've tried 7 pairs of headphones with different combinations ><
Where's the "Audio Input" to my car stereo? I've got a tape player/radio in front and a multi CD changer (wireless control) hooked into it. Crawling under the dash of today's cars ain't exactly fun, so some directions could help.
Take a look at this, this panel has a Stereo/AUX input<br/><a rel="nofollow" href="http://www.lunaimports.net/servlet/Detail?no=92">Stereo/AUX input</a><br/><br/>It also depends on your car stereo system. Not all of them have that input. <br/>
I thought the point was not to spend a lot of money. $199 is a lot of money. Even more than just buying flat out battery powered iPod speakers and putting them in your car.
$199?? What is this about?
It says that at the top of the page your link goes to.
Isn't it the same thing? Doesn't really look like you're making a difference. Sometimes you can buy those audio tape things, and it has a cable for the iPod input or whatever. That's what I do.
Yeh, it is the same cable that you can purchase in a store. The key point is that you can recycle your broken earphones and make something useful. Things aren't cheap in every country, at least not in mine.
Hmmm...I had one of those cables sitting around. I plugged that into a converter and then into a guitar amp. It's really loud!
So when plugged into a car headphone jack, it will play the music from the iPod?
Not the headphone, the other end goes to the 'audio input' of your car stereo.
