OHMS AND WATTS!?!?

Discussion in 'Amps and Cabs [BG]' started by stompfrog, Feb 21, 2005.


  1. HELLO ONE AND ALL!

    I HAVE A WARWICK QUAD VI HEAD
    http://www.warwickbass.com/amps/amps11.htm
    IT IS RATED 600W AT 4OHM

    CURRENTLY I HAVE ONE CAB WHICH IS THE WARWICK PRO115
    http://www.warwickbass.com/amps/amps07.htm#115
    WHICH IS RATED AT 400W AND IS 8 OHMS.

    IF I ADDED A WARWICK PRO210 CAB TO THE RIG WHAT WOULD HAPPEN?
    http://www.warwickbass.com/amps/amps07.htm#211
    ALSO RATED AT 400W AT 8 OHMS


    I UNDERSTAND THAT 8OHM + 8OHM = 4 OHM WHICH WOULD SUIT THE HEAD FINE HOWEVER....

    ARE TWO 400 WATT CABS GOING TO BLOW IF CONNECTED TO A 600 WATT HEAD OR ARE THE CABS ACTUALLY 800 WATTS (400 +400) AND ALL WILL BE FINE?

    THE BOTTOM LINE IS - - - - -

    IS THE 600WATT/8OHM HEAD SAFE TO USE WITH A 210 400W 8OHM AND A 115 400W 8OHM CABS.

    MANY THANKS

    HOPE THIS IS CLEAR, IF NOT JUST ASK AND I WILL CLARIFY.
     
  2. CAPITALS=SHOUTING!

    As you suggested, two 8 ohm cabs will split the power equally between them, so they will be safe to use with a 600 watt head.

    Hi there, Stompfrog! I think there is a wealth of info in the FAQs section about wattages and impedances, but, as a quick answer, yes you are correct.

    The two cabs, linked in this manner will give you the 4 Ohms that the amp is looking for, and yes your available headroom will be 800 watts.
    You are unlikely to cause damage where power ratings are concerned in this scenario.
