Picture of DIY Portable Boombox (from SCRATCH!)
Time to party! Let's rock the house! Today I will show you how to make a boombox that sounds like a genuine audiophile speaker. It's made from 100% scratch. I added an iPod docking feature, it also works with any kind of MP3 player with an auxiliary output, it also has a 2 channel RCA output. I even added an USB/SD card audio player with a remote control for the Boombox!  The Total cost was $46.16 (Converted Price from "Philippine Peso")

I made this guide as specific and as step by step as I can, the only thing that dragged me down from finishing my boombox early, was the documentation for instructables that I did for this project. I hope you enjoy it!

My version was so efficient that it even had the capability to beat or match-up the sound of the Monster™ Beatbox (by Dr. Dre), Zeppeline™ Air, Altec Lancing™ IMT800 and IM7. My boombox has the capability to release a clean, deep and low bass, with the perfect midrange level and has a spectacular treble that seems to sooth the ear. It has a two way speaker system which will definitely reduce the amount of distortion given off by the speakers thus improving your audio experience. 

Frequency response: 45Hz-20kHz
Max Amplifier Wattage: 2x30W Stereo
Total Harmonic Distortion (THD): 0.1%THD 
Max Speaker Wattage: 150W-200W RMS
Speaker Size: Woofer (5.25"), Fullrange (1.75")
Enclosure's Dimensions: H= 5.75", L= 19", D=6"
Other Feature's: iPod Dock, USB Media Reader, IR Remote, Bass Trebble Equalizer and etc.
Audio Input Type: RCA, Auxiliary (3.5 Stereo) and 30 pin iPod Dock.

This project is ideal for: Picnics, Parties, Car Road Trips, Home Use and etc.

If you don't have time reading the long texts, there are summaries written in bright red text below each step.

"It takes pure craftsmanship and experience to build a highly efficient boombox from scraps and pieces. "

This is so awesome, I'm ordering parts for it now. Do you know how to make this battery powered?
ASCAS (author)  junglebrad3 years ago
Yes! Simply connect the battery to your amp's power input.

I was just looking through some of your work - including this boombox project. I must say you do a beautiful job of presenting the material. Pictures are excellent. Wow - if you still have a lot of school to go - you have a HUGE headstart on your peers! Thanks for sharing your hard work.

Nicely done!

I like it, it's cool that you used wood in that application.
ASCAS (author)  vroom...vroom...3 years ago
There's another type of material, you can use MDF. Those kinds of woods are specially designed for speakers, it's not actually wood since it's man made.

How can you add Bluetooth to this?

if i want it to incorporate a decent battery, what do you suggest?

ASCAS (author)  george.winstong7 months ago

I would suggest assembling a 18650 Li-ion battery pack.

I like how your directions and also how this unit looks better than all the others i have found. I want to build one similar to this, please please write back as soon as possible. I want to start this weekend. thank you.
