20W Recycled Speaker Cheap and Easy!






Hi everyone!
I found some old speakers which we didn't use so I thought lets make something nice of them :)
I designed a wooden box to put them in and painted it.
The speakers I found are two 40W 6ohm speakers, one of them is for the low frequency (the bass) and the other is the middle frequency.
I bought a amplifier on ebay for 3$ and the quallity is really amazing!
I also found a 12V 2A adapter from a led strip which I didn't use and they were perfect for this project.
Collect the Parts You Need






What do you need?
- Amplifier: Ebay
This amplifier needs 6-12V and 2A is enough for 2 speakers in parallel.
When you have 2 big speakers which are the same and you want stereo audio, I would really recommand this amplifier: Ebay
- Speakers
Just search for some speakers which are 20w or more and a resistance of the speakers between 4ohm - 12ohm
- Adapter 6-12V and more than 1.5A output
- Aux input
- Wires
- Piece of rubber or a passive speaker if you have one
Put the Parts Together






Connect the parts with wires which you can see in the picture.
I also added 4 LED's at the top and a toggle switch.
Design a Box





I used wood to make the box, painted it and I'm so happy with the result :)
