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
On button there are 2 switches " mono" and "Stereo" for A and B channels .
What's the active xover? never ran it before, but heard of it.
