This is the Bluetooth 2.1 Heineken 5L mini keg speaker that I built. This is the second "prototype" that I have built, the first one was powered by an old laptop power supply meaning it wasn't portable. This version is currently being powered by a 20v 1.3Ah drill battery that is soon going to be replaced with two of the 12v 1.5Ah blue batteries seen on my desk in the video. The amplifier board is a sure electronics board, sending full range signal to two cross overs pushing the Kicker 5.25" KS series components. I do have plans on a 3rd and final version on the keg speaker that will include Kickers new 6.75" CompRT subwoofer and their top of the line 6.5" QS series components.
