I have a JL 250/1 and I m currently running a 10W1 4ohm. I am about to hook up my 10W3 2ohm. The guy at the local sound shop said hook it up just as I have it now. Is this correct?? I do not fuly understand the ohm thing. The only thing I think I know is 2 ohm is more efficient than 4,6 ohm........correct.
