Silly question, since I think I know the answer, but can you plug a combo amp into a stack-style speaker?

I figured you could, but thought I'd ask first. I wish to get a new amp in the future, but I don't have the space/room for a full stack or even a half. Instead, I'd do best to get a combo, and if I can ever improve and get room, I could buy speakers, then use it like a head.

stack-style as in speaker cabinet? if the combo amp has a speaker output then yes. if not, don't just use the headphone jack because it will not work (an impedance issue).

also, if your amp does have a speaker jack and you have a cab, make sure you use a good gauge SPEAKER cable (16 avg is a generally good gauge, the lower the better), NOT just a guitar cable. it will toss your sound and possibly damage your speaker.
