I'm assuming you mean 1.5 cu ft per sub, and a sealed box. Anyway, they should be in the mid to high 130s, possibly 140s. It also depends on the vehicle.

Moses, what size Brahma are you talking about? A Brahma 12 will be in the 140s in a ported box, like Wahl said, while the 15" CAN approach 150 db if the box is right and the vehicle is good for it.
