on my valve king 212 the speakers connect with one cable, leaving one open. now the ohm selector has 4ohm 8ohm 16ohm settings and it says "4ohm min. speaker jacks paralleled" so does that mean it needs to be set on like 8 or 16 to just run the combo im confused.
It needs to match the speakers that are in there, if it has two 8 ohm speakers in series its 16 ohm, if they are parallel it's 4 ohms. If it has two 16 ohm speakers in parallel it's 8 ohms and two 4 ohm speakers in series is 8 ohms.
it has 2 - 16 olm speakers so it needs to be set on 8 right?
Yeah, they're probably wired in parallel, if they were in series it would be 32 ohms and guitar amps don't have out that high as far as I know.
