Ok, I obviously was never taught this, and did not pay attention to physics class in high school, so this is my stupid question for the week. How does the "X" wattage at "Y" ohms that a head puts out relate to the "Z" power handling at "Y" ohms that the cabinet takes? If the "Y" ohms do not match up, and I going to screw up my equipment? I have seen alot of people talking about the ohms of certain cabinets and heads on these forums, and I honestly have no idea what is going on. If anyone could help me with my ignorance, I would appreciate it. By the way, I am using a Hartke 5000 head with a mid 90's Carvin 2-10 and 1-15. Could not tell you the ohms of the stuff if my life depended on it, which if I end up blowing my rig up with me in front of it, my life just might.
