hi everyone i just bought a new rig and i can't quite figure it out. this is my first actual amp and cab, not combo. My hartke 7000 head says that if you run an 8ohm cab its runs at 200 watts and if you run a 4 ohm cab it runs at 350 watts. Ok sounds cool, but on the back where u plug the cabs in all the inputs say 8ohms next to them. So did the manual lie, can i only run my head at 200 watts? Also any good info you can give me about the hartke 7000 head would be helpful, and not sell it hartke's suck, cuz i really like it, just helpful info please.
