Outlaw has not released that information yet, I'm afraid. I actually went back to the Model 1050 PDF data sheet ( available here ) to see if it said anything that might give us a clue, but it did not list 4ohm or 6ohm power levels. We should be seeing more information in the next couple weeks, though, and if this is not included in that information I'd suggest asking Outlaw's tech support team directly (they have a web support page , or you can give them a call).
