Like a lot of you I have a lot of old projects laying around unused so I decided to make a deck bluetooth boom box out of some decent but unused old stuff. Inspiration came from an old picnic set that I ran across in a thrift shop. I stuffed an old MRefC chip amp, a Subbu DAC, a Kookabarra preamp, and an ebay bluetooth gismo into the case and added power. Easy to transport and sounds great. Using Mark Audio full range speakers.
