Bought this custom box a while back but I'm going with a single 12.

Might need interior mods to fit it depending on your options/trim.

Really heavy duty... this thing is SOLID!

Don't know anything about box design but this looks well made and appears to be a 4th order.

No idea what the cF is, but it's big. Takes up the entire well.

Big port but sure what it was tuned for.

Pickup only in Townsend MA.

Bring me something to drink and it's yours.
