Hutzal/Mojo:
You guys are right, it is 4 ohms if driven in parallel.
Thanks for the clarification and info.
Now that the 8/4 ohm qustion is settled, the decision for me is do i get a M80 or a M60.
Once i make up my mind, will post on the board. For those of you interested, please see link to my home theatre below.
