So I have a Rogue Tuberider 1000mvt head. Which is rated at 8 ohms 100 watts. I am building a 2X12 cabinet and was wanting to know about ohmage and wattage. If I hook up 2 4ohm series wired that gives me 8 ohms correct? Now does wattage combine like ohms? So can i run up to 100 watts for each and then they drop to 50 watts? It's my first project and I'm trying not to rack my brain or fry the head. All suggestions would be greatly appreciated.
