If that pic doesnt work heres the site...

Anyhow So im starting to make the little gem but i am going to be using a 40 watt 8 ohm speaker...I know the power changes which im not worried about right now but wat other changes will i have to make so that it can run on a 40 w if there is any.
there isnt.

the amp is half a watt. As long as your speaker is atleast half a watt your fine.
my little gem is inside an old radio wth a .3 watt speaker. Which means itll probably blow out eventually. But its so low I dont think it would make a big difference
