According to Floyd, the boombox is powered by a Pyle Pro stereo amplifier, with the speakers bought second hand from a thrift shop and with plywood being used as the front panel. Unfortunately it does not appear that Floyd is selling his creation since his website does not appear to have any sort of online store, but we’re sure if you really wanted one for yourself, you might be able to work something out with him.
However if you’re more of the hands-on type of guy, you could try making one yourself by watching the video below of Floyd appearing on the Craftsman Experience teaching the audience how to make a toolbox boombox for themselves.
