i had it in a 2. cu box at 32hz and it sounded like ***.
unless someone has some tl scores or a video i think ill keep this one. and i really put a lot into this box unlike my last one. the final for that was 1.59 cu @ 35hz (before sub displacement)
also, im not giving it the full 1000 rms, its wired to 2 ohms and my sub does 725 at 2 ohms.
