GK only does 8 and 4 ohms HLF only has 4ohms out. I came across a steal of a deal and now have 2 HLF's. I wanna stack em on there sides and make myself an 8x10. Anyway I can re-wire these cabs to 8ohms? or combination of connecting them otgether to get 8 ohms? Does memory serve me right that if I run my head into cab one, then cab 1 into cab 2, will that give me a usable 8 ohms? Do I just need to use an external power amp? (not ideal) Suggestions are welcome.
