I'm gonna order one of those 200w and try it too. Just because I'm curious lol. It was a fun build I'm curious how I can improve it the 2nd go around lol.
I don't know a whole lot about stereos and how sound electronics work but I'm curious if you could hook two speaker wires into the same terminal and have 2 left and 2 right speakers (total of 4) instead of just 2?
