My Peavey Classic 50 has 2 speaker outs, 1 - 16ohm,
and 1 - 8ohm. When both are plugged in, the amp
runs at 8ohms. When just the amps speakers are
plugged in, they're in the 16ohm spot. If I were
to run another cab along with the amps speakers, the
cab would need to be a 16ohm cab right? So, in other
words, if I wanted to run my Marshall 1960a 4x12 cab
along with the amps 2x12's, I would plug the extra
speaker out into the 16 ohm input of the Marshall and
that would give the amp an 8ohm load right?
