My amp can be changed from 4,8, and 16 ohms, however, I don't exactly understand what this means. What kind of sound does each setting give and is any better than another?

it`s to do with the speaker impedance

if you have 1x16 ohm speaker.......select 16 ohm (112)
if you have 2x16ohm .......................8 ohm(212)
...................4x16ohm........................4 ohm(412)

simples

not having the right speaker impedance selected risks damaging the amp. leave it in the config you bought it in, unless your changing your speaker config.

Typically, your guitar cabinet will have an ohm rating but if you are running multiple cabinets the some math should be done and you have to know if you want to run the cabs series or parallel and luckily there are columns and posts with the formula to calculate.

it depends on the actual speaker ohm ratings and the formula but if they are both rated at 16 ohms IG is correct with the 8 ohm theory.

The impedance rating does not change your sound.

If those were all wired in parallel. Important detail you missed.

If you have a combo, why are you worried about adding another cab?
