lol I need 2 channel amp, so i'm guessing it's 90wrms @ 4ohm? What about gains and other stuff, how do i tune that? btw, payed $8 for it.
See the lil black gain pots on the board there should be holes in the heatsink for them that's the gain left and right for each channel
found the gain you were talking about. But, which one is what?
