4 Cu. Ft. Custom-Ported MDF Subwoofer Enclosure for (2) 12" Round Subs (4.0 @ 32Hz)

Your box is tuned way to high 42Hz this box is slightly smaller and tuned at 32Hz a much better option.

those are meh at best. Got a used one for cheap 30 bucks for my buddy (hint the guys that sell that box online is right down the street from me). Sound okay, doesnt get loud nor low, just slightly lower than prefabs but gives up output overall. Better to just spend that on a real custom box.

While output should be much better it's also twice the price. At $250 You could have a real custom box made to fit his vehicle. My suggestion was a similar priced box as to what he was looking at but a much more daily friendly tune than the prefab he was looking at.
