My cab has 4 16ohm speakers wired for 16ohms.
Can I re-wire to drop it down to 8ohms? And how?
I'd just like to match it up to my amp to get optimum performance.
Ummmm I don't think you can get 8 ohms out of 4 4 ohm speakers. You could get 4 ohms but that'd probably blow your amp . I could be wrong, but I can't think of any combination that'd give 8 ohms. Does your head not have a selector switch?
