The tiny, yet powerful MAX9744 can pump 20 watts of audio to power two stereo speakers. In this tutorial, we going to upgrade a pair of old school Apple Pro Speakers and hook them up to this bodacious amplifier.  
  
This lovely kit includes a power filter capacitor, terminal blocks and a 1k potentiometer to adjust volume. A 3d printed enclosure will houses the components and can be printed in any color to match your style. A 3d printed volume knob in ninjaflex filament makes a panel mount 1k potentiometer smooth to the touch.
