    If your amp can handle 2ohm load, then probably yes.

    2 x 4ohm = 2ohm load.


    How many watts is the amp and the boxes?

    amp is 300 watts the boxes are 800 watts each!!
    I know it says that it can be done but a few people have told me that it probably isnt safe and i could end up blowing something!!

    Yeah, there are things that you have to be aware of.
    First off, you have to know if your amp can handle 2ohms. If it can´t, then you´ll blow it by plugging those boxes into it.

    But I´m sure that there are ppl here which know so much more about this stuff than I do, so I hope they´ll maybe throw in some advice here.

    DISCLAIMER: I DON'T own the SVT-II so I may be wrong. Use this advice at your own risk.

    Sorry, but I would hate to have you blow your amp because my advice was wrong. Please double check for your own good.

    I downloaded the Ampeg SVT-II manual from www.ampeg.com and it says that there is a speaker impedance selector switch that will let you select between 2 or 4 ohms. It appears that yes, you can run those cabs as long as the cabs RMS power ratings can handle the power. For a 2ohm load on the amp, it would be (2)4ohm cabs in parallel. For 4 ohms, it would be (2)8ohm cabs in parallel.

    Hope this helps.
     
  6. Pick,

    Lovin' Bass is correct. Not only is it OK to run that amp with 2 4 Ohm cabinets that's actually what the amp was designed to do. The SVT II is based on the original SVT which drove 2 4 ohm 810 cabs (because one of the original 810s couldn't take the power! :D). They haven't changed that so it's cool. Also if your cabs can handle 800W a piece, it's almost impossible to blow them with that amp. Underpowering cabinets is kind of a myth. In the 2 cab configuration it will put 150 W clean power into each box. Even if you get it pretty distorted it won't put out anything close to 800 W per box. So you're safe.:D
    cheers!
