Step 1: Materials and Tools
Bucket with top cap
Woofer or midrange speaker
You can find schematic diagrams of your preferred amplifier on the internet.
choose the one that matches your speaker's specifications.
We chose TDA 2003 because it requires very few external components and low power consumption.
-TDA 2003 (scrapped from old car stereo)
-2pcs 100uf capacitors
-2pcs 1N007 rectifier diode
-12v 1A transformer (you can use your old PC's power supply)
Power supply (12v/18v depending on your amplifier)
Female RCA jacks
3.5mm jack to RCA cable
Spray paint (optional)
It seems that the materials seems to be numerous, but the end product would be beneficial.
It's sound is comparable to a decent speaker system that costs many times than this project.
Step 2: Construction of Amplifier Circuit
Step 3: Putting It All Together
Second : Screw the power and amplifier circuit at base of the bucket.
Third : Puncture hole at the side of he bucket to insert the RCA ports and the power cord.
Fourth : Seal the slits at the cap top using glue stick and the other areas with holes.
Step 4: Try It!!!!
In our case the sound is good and much clearer. It is because of the tweeter and the bucket is sealed ,you can hear low frequencies resulting to better sound quality.
