Under-helm sub box dimensions

[LoneWolf2]

Anyone happen to know the dimensions of the space under the captains area on a mondo? Going to pull my sub out of the helm hole and stick it in a box so I can actually hear it, but can't remember what the dimensions are for that space under there (and the boat is 2hr away at the marina).

That's going to depend on the sub itself also . Keeping factory I'm guessing ? Or are you doing a new sub as well ? Are you going sealed or free air?
