Ok heres the deal. I've got a Hartke 2000 head and a 4x10 cab. The Hartke is 200 wts @ 4 ohms and the cab is 600 wts @ 8 ohms. What is it gonna do when I plug it in? I know the ohms are the resistance but I dont know if the 200wts will be cut in half in the cab or if the full 200 will be pushed to the cab with room to spare. How does this crap work?
