I have converted a 3 way set of pc speakers system unto bluethooth it works great and so happy i am having to use 2 psu as i wanted to take 12dc from the amp board inside the speakers but its 12vac converted to 12v dc but when i conected the bluethooth amp itbuzzes like hell not to worry it still work great great for building a little boombox having the bluetooth receiver on the same board eliminates extra wiring and annoying crosstalk

I installed this on my boat and its awesome just bought this to start a new project and didnt think it would be much but this little thing is mind blowing i took 2 book shelf speakers wired them up and turned it on this thing is impressive it sounds as good as my 250 dollar bluetooth speaker if not better and i can take it everywhere im considering buying 2 more just have laying around the house good for the price
