Does anyone have the specs for the Fi BTL 15" subs. I am installing 2 of them for a customer, but he doesn't have any perameters for the subs. He is putting a Hifonics Brutus 2600 watt RMS d class amp on each sub. It is going to be in an old school s-10 2-door Blazer walled off right behind the front seats. Built for competition only, wanting to hit the biggest legal spl number at USAC competition. Any help would be appreciated. Thanks

    BTL 15 � Ported box we recommend using 3-5 cubic feet @ 30-35Hz. Again use 12-16 square inches of vent area per cubic foot of volume

    You might want to tune higher since its strictly for competition purposes. Its going to take alot of testing with different enclosures tuned to different hz to get the maximum score
