I hope this is not a repost, cuz I looked around. But anyway, I am assuming I can rewire my 4 ohm cab to 8 ohm without to much trouble, right? I have a 2-12 cab that has 2 8 ohm speakers wired to 4 ohms. I just picked up a 15 cab I want to run with it. That has a 4 ohm speaker in it. I think if I just plug er in, I'd be running only 2 ohms and mught damage my head. What do you guys think?
