This box is marked as “tuned to 35” which I doubt but it is violently loud between 42-60Hertz! Yes I said VIOLENT BASS!! I have 4 skars SVR 900 watts each with a Taramps 3000.1 bass amp. Good Lord my organs rattle.
Great box and it fits great in my 2022 Silverado 3500HD CrewCab Longbed Duramax Diesel.
