Hey there

well , another boombox on the way 
and this time i decided to make it the smallest that i can , real miniature - so that i can carry it freely to the beach without grumbling on the weight issue.

hope you enjoy!

Step 1: Shopping List

Picture of Shopping List

so , for this Instructable i decided to build something modest , small , and yet COOL.

i bought a used Center speaker 
new Sealed Lead 12volt 5amp Battery
A variety of bolts and nuts
a few angles
small LEPAI amp from eBay
Plexiglas - had at home a piece of 1x1 meter

The tools needed are :
drill bit + drill
Tin snips
solder + tin
Screwdrivers and/or electric screwdriver

that`s it in general

Step 2: Cutting the Plexiglass

measure the size of the desired BOOMBOX and cut it using the saw.

over all we need :
Bottom piece
upper piece
two sides
and one back piece

Step 4: Cutting the Side Angles

Found some old Angles on my warehouse

cut them with the  saw and assembled them to Plexiglas angles

Due to weight issue ( the Battery ) i had to use at the bottom a strong kinda heavy angle

Step 5: Assemble All Pieces

Step 6: Create Bottom Legs

Step 7: Create Internal Support Angles for the Rear Plexiglas

In order for the Boombox to be stable and not shiver we need to strengthen it via Small angles

Step 8: Tear Down the Plexiglas Protection Nylon

Hi, nice job! But does the cabinet rattle or make noise at higher volume levels? If so, did you seal the corners later on? I am thinking of doing something like this myself.

Hi, great build. Could you provide more detail on how you charge the battery and use the battery at the same time? Thank you, Tater

great instructible! quick question, can you charge the battery while using the battery in this set up?

RoeyLeon (author)WillERoberts2013-08-15


yep , you can charge it as much as you want during the phase that it is being used by the system

No need for a low-pass filter to the woofer?

I need indeed , but I didn't have at the time of constructing it

Ordered from eBay a few Crossovers
