    Just picked up a Bergantino NV610 (4 ohms)to use with my old Sunn 2000s tube heads (4/8 ohms).
    First cab I've had with duel inputs. Is it possiable to run two heads into the single 4 ohm cabinet to double up on power without damage to the amps?

    No, it will cause problems with both and cost a lot of money to fix.
  4. Don't do it!

    You're talking about switching between two amps, he wants to run both at the same time. Bad idea.

    nice thread, I always wondered and never had the guts to do it!
  7. oooh. My bad. right-o.

    whatevs, good to know about anyhow
  8. Not sure if I'm right, but it will send the powered output of one amp, send that power back to the other amp and fry it, while the other amp's trying to do that too, and you'll end up with two fryed amps.

    Am I right? :meh:

    The cabinet does not have two inputs. It has a pair of jacks wired together, so you can daisy-chain another cabinet.

    Great, Thanks for the feedback. Certainly not worth damaging anything over. I'll just split the signal with an A/B box before the amps and take out the Sunn 2x15 cab if needed.

    Oh come on! You guys always let 'em off easy. The best way to learn is the hard way. What happened to "Go ahead and stick that fork in the socket! I bet it's the last time you'll do that!" :D LOL

    But seriously, don't do it.

    Theoretically, You can re wire the cab like 4X10 + 2X10, I have no idea what would it sound like, I'd assume pretty bad.You better know what are doing, or else...
    You'll also have to change/replace the cab's input jacks wiring...

    So yes, I see no problem doing that, but I wouldn't do it, sounds like trouble.

    If the speakers are in different compartments it might work well, I don't know this cab from inside...

    In other words, don't do it :)

    Just grab a second cab, like an Avatar - smaller and less 'spensive - to run the other head into.
