Learn the basics of audio amplification and design your own speaker cabinet to suit your style with our latest Weekend Project, the MonoBox Powered Speaker. MAKE contributor and audiophile Ross Hershberger designed this project around the popular LM386 audio amplifier, a low-power, but highly capable IC. The circuit is designed to accept power supplies ranging from 6V-15V, making it easily adaptable to your car’s 12V power plug, a 9V battery, or a 6V wall wart. The MonoBox has no volume control. Instead volume is controlled by your input source. So be ready, because this amp packs a punch!

Watch the video below to see how to assemble the circuit and install it inside a cigar box. This is a great project to give your own signature touch. The choice of speaker size and shape, grille material, and enclosure are entirely up to you. And since no two will be the same, be sure to send us pictures of your custom MonoBox.
