Wow, is the ep800 big. like wow. But here's the thing. This is the in-cabinet version and it has 4, yes, 4 sets of binding posts. And there are 4 on the amp they sent. Do I really need to hook up 4 pair of speaker wires to it? I hope not. I only ran one in the theater for it and the walls are already up. Anyone from Axiom or that has experience with big ass subs, please help!
