Granted this is a pretty basic question, but I can't find the answer anywhere. Will an iAmp 800, with its 2 speakon connectors wired +1/-1, run 2 8-ohm cabinets in series at 16 ohms (not what I'm hoping for, and generally a bad thing in my book), or are the connectors parallel, causing the total load to be 4-ohms. I guess what's throwing me is the +1/-1 bit. I don't really understand what that means. In short: iAmp 800-speaker outputs series or parallel?
