I am getting the Gallien Krueger 1001RB. Its 540W at 4 ohms. I'm getting a 212 to start, and then eventually a 410 or something of the sort. Now, to make sure I get the max power from my amp, I would want to get both cabs at 8 ohms, right? It would just mean that I would get only 340W for awhile, until I get my other cab. (This is what the head puts out at 8 ohms). Am my right on this, just wanted to make sure before hand.
