Well you are right. I meant that there is a switch for either 4ohm (or 6ohm) or 8ohm (or above). Below 4ohm is a no no and the best quality (recommended) is 8ohm. What I'm getting from you is that a 200 Amp is good enough if the connection (series or parallel) falls in the acceptable impedance range_not below 4ohms in this case? Am I anticipating too much??? By the way__thank you for taking time with this Michael
