Question about powered sub.

[Schmuck 1]

i have a KLH 10" side firing powered sub. On the amp it has speaker terminals and i remember reading and seeing pics in the manual about hooking speakers up to that same amp but I do not remember what it said and I do not have the manual. Does anyone know what I am talking about, sorry I can not explain it any better. If you know what I am talking about how would I hook up more speakers?

it's a full range output most likely for hooking up satellite speakers or to do a 2.1 setup.
