ok i posted something similar to this a while back but i wanna be more understanding of it, i own a Crate Flexwave 65/112 and i want to connect it to an extension cab, the only thing is that i still dont have a full understanding of how to go about it since i dont understand fully about Ohms and stuff. so heres the specs of it. If possible, can i plug it into a 4x12 cabinet or what do you all suggest.
