It will be the smallest box possible sealed or ported, which is .5ft and 1ft. I'm using alpine pdxv9. The idq is 500rms and the SA is 600rms. I understand at the idq is SQ sub over the sundown, however, I question how much of a better "sound quality" am I receiving from the idq over the sundown? Also, would hear a noticeable increase in spl with the sundown over the idq with my current sub? Is it a matter that you would recommend one sub over the other based on the box I choose?
Reconing it is not really an option. The reconing kit is $100 and shipping it is $30. I'm getting it done at cost basically because its already at ID.
So based on all that, what say you?
