I was wondering about this at work today and was curious if somebody could answer this for me... What would/wouldn't happen if I ran a 4ohm cab and an 8ohm cab at the same time? Would the 4ohm run at 4 and the 8 run at 8? Would they each run at 8 (and could this put the 4ohm cabs at risk)? Would they each run at 4 and possible damage the 8ohm cab? This may be a commonly known fact but I just can't say I know the answer. Any input would be appreciated!
