    I have no idea...i can't use BBP6


    i dunno why people always show that "maximum acoustic power" graph...it doesn't mean anything...i wouldn't worry about it.

    i hit 140.4 db in bassbox with a 10" cerwin vega stroker, you would think 4 18's would put out a lot more.

    tell BB6 to do a vented box and choose "suggest" then choose "high output" then change the hz to around 35-37.

    yes it's suggest fb but that only gives you a rough idea, i don't use it. How much power are you pushing? 8000 watts? Can you post the specs of your subs.
