    on the back of my peavey head it says:
    400w/2 ohms 28v rms
    250w/4 ohms 31.6v rms

    now when i ordered my cab the guy said to me are you going to only be using this one cab (4x10). i said yes i wont need any more cabs thanks.
    so he sent me a 4ohm cab.

    now does this mean im only getting 250w from my setup?

    Yes, you will only get 250 watts. But, you dont get (at least not typically) 2 ohm cabs.

    No other way around, unfortunately, for you. There are no commercially made 2 ohm cabs. But, the difference between 250 and 400 watts is not that much, really, and adding another cab would make the rig louder reguardless.

    You don't. If your rig isn't loud enough add another identical 4x10 and you'll get 6dB higher output.

    It does, but it's moot. The difference in level between speakers driven by 400w versus 250w is about 2dB, which is inconsequential.

    if you could exchange your cab for the 8 ohm one, you could then wire it @ 2 ohms.....

    truly, it probably wont make a *huge* difference in volume. you will probably gain a *little* headroom, as most probably, that sort of cab will be putting out similar volumes whether driven with 250 watts or 400 watts. however, if you just need a *little* more, then the 2 ohm load may deliver that.

    best option for *more* is another cab, as mentioned above.

    or if youd rather, what BFM said....

    hmm if you guys dont think jumping from 250w to a 400w will make much difference then im not going to bother doing anything. maybe i could use the high gain input even though my bass is active. that should post the volume a couple of dbs.

    As long as you don't hear distortion in the preamp, there's no reason not to use the high gain input.

    S.P.

    That Peavey head is 2 ohm stable .... when you can, get another 4 ohm, 4x10 or a 1x15 cabinet ..... my experience with the older Peavey heads is they have a tendency to clip very easly in the preamp stage ...when using a hot input ( I have my bass with SD Quarter Pounders ) ...I have to set the preamp volume (Firebass 700 ) at about 9 o'clock and that keep the preamp from clipping ( when it clips, it really sounds crappy ) also when using the active button it kinda sounds constrained ...I've been using a VT pedal as the preamp and have it plugged in the power amp in and that has solved my issues with the preamp clipping ....all in all I'd get another 4 ohm cabinet, you'll like the sound and you'll have the ability to have a big rig when needed
