hey guys!, i recently purchased an Alpine type X 12" in a prefab box, which isn't the greatest. So im trying to design a new box, i have an idea in mind but dont know if its correct. I've been doing some research and i know that the box needs to be/have

1.8 - 2.5 cubic ft3

29-35 Hz

29+ spin of port area.

So heres the box i think i designed properly


Also, i have a Mtx tc600.1 amp. Its going into a 1993 Toyota Camry

Any suggestions, help is appreciated! Thank you!
