i need help chosing a sub

[marshall]

i plan on buying one sub, i am buying a Rockford Fosgate Power T2500 amp which people have said it has come with 3k on the birth sheet, but i am debating between the Orion HCCA 12.4 or the FI BTL 12...which one would sound the best and cause the most flex?

well flex would sound BAD. Flex is a bad thing to have, damage on the car and damage to the sound quality. I would choose of the two options given the BTL, I had one before and it did very well.
