So, if I'm someone with very little electrical/electronics knowledge and never used a soldering iron, how hard and dangerous would it be to build my own amp with Purifi or Hypex modules, ideally one that would also have a 12v trigger and both XLR and RCA inputs with a switch to toggle between either input, and perhaps a buffer (I think that's what it's called?) or some other circuitry that would eliminate any plops being sent to the speaker when switching on/off the amp?
