Suitable battery-powered amp

posted Aug 06, 2017 19:14:53 by Jacob Gresham-Hill
Hello,

I'm trying to build a project with the MOVI board, however I cannot get it to drive a 32ohm speaker loud enough to hear across a room, I also want it to run on batteries. Can anyone please recommend an amp that can meet these needs? Thank you.
