I am using a vintage 30 and a G12H-30 in a 2x12 cab. I know the vintage 30 should be louder, but am wondering if there will be any amp issues using them. Both are 16ohm wired separately to make 8ohm load, two jacks each one to a speaker, two speaker cords. When playing them i dont notice the vintage being noticebly louder. Playing out of a 40c on full power.
