Say running a 4 ohm cab + an 8 ohm cab into an amp that has a low min. impedance of 4 ohms? I know this sounds silly but I just found that I can only run the one cab I have now with the amp I have, and wonder if I should DEFINATELY sell it immediately for a loss and pick up TWO more cabs, or if there's no need, and just keep it. I know, a) this sounds stupid, there's a minimum impedance for a reason and b) I should do my research BEFORE i buy, but i guess I wouldn't mind hearing it from someone else before I sell / rebuy. Thanks guys!
