Hey guys, I have a show tomorrow and I will be using a GK 1001RB-II head with an 8ohm Avatar 2x12. However I'm not loud enough, I'm in an Alaskan Thrash Metal band called "The Shotgun Approach" for all you myspacers out there. So, I can either run her through the PA or run my rig with an old Peavy 2x15. Only problem is, the Peavy is 4ohms and coupled with my rig in parallel there is 2.67 ohms impeadence. My head can only handle 4ohms. So, the only other option I have is to run it in series and get 12 ohms of resistence. Only, is it a good idea to be doing that? I think my head can opperate up to 16 ohms so it sounds like it might work but the whole mixing cabinet ohm's thing is kinda shaky sounding. If you guys could respond as soon as possible, that would be great. Tomorrow is showtime (first show oh yeah).
