Picture of How to Wire a Speaker to 3.5mm Jack

In this Instructable, This is my first, I'll be showing you how to wire a regular 3.5mm headphone cable to a speaker. I'll try to be as clear a possible, and if you need help just ask. And I am NOT responsible for any damage to anything you have made a mistake, PS. there is a very very low risk of causing a damage With that out of the way, LET"S GET STARTED!!

Step 1: Materials

Picture of Materials

- Mp3 Player
- Speaker( Higher Watt Speakers are quieter because it is hard for the mp3 to push the speaker)
- X-acto Knife
- 3.5mm Wire
- Hot Glue Hun
- Hot Glue

Optional Tools:
- Solder pen/gun(Good for long term use)
- Flux/Solder
- Electrical Tape
- Lighter

Step 2: Stripping the Wire

Get your X-acto knife and headphones(That you don't need) then carefully cut about an inch under the part where the headphones splits. Then pull the casing off. Get your lighter and quickly burn the tips. Ok, My headphones had a copper and green wires on one side and red and copper on the other. Bout sides act as connections for speakers.

Step 3: Connect the Speaker and Wire

I know this part is complex to some so I'll elaborate as much as possible. Get one side of the wire, as in either the green and copper side or red and copper side. Oh, I'd prefer if you cut off the wires from the speakers. Get your headphone wires and put one on positive and one on negative. It doesn't matter which goes one which. Plug it in to your mp3 player and touch the wires on the speaker till' you get a sound. Hold them there and hot glue them down. The Hot Glue is temp. This part may take hours, so relax and understand that you weren't the only one having problems connecting the speakers Contact me if you are having problems.

Step 4: Finsihing Up

You can solder the wires later. Well your done(Hopefully). I'm trying to amplify the speaker because it is quiet. While thanx for watching:D

it is not loud

you'll need an amp to increase the current running through the cables to match the wattage of the speakers

how would i connect 2 speakers to a single 3.5 mm to get that dual channel going?

the headphone cable splits about halfway to go to each earbud. use each side of the cable for a speaker, et voila, dual speakers.

Hi. I'm connecting the wires exactly like in the instructable, but for some reason I STILL can't get it to work. Can someone please help me?

Look if you don't find it useful then don't comment. Obviously you guys are smarter than everyone else so keep your negative comments to yourselves.

I have a pair of headphones with speakers bigger than that installed into it. Why do you have to post such pointless stuff.

pancho del rancho (author)2009-09-08

ITS KINDA OBVIOUS HOW TO DI THIS but you should really have a amp and a mp3 line will make it way easier
