    wow u want an inefficient sub to be in the high 140's
    all i can say is slap it in 5 cubes tuned to 40hz with 60 square inch port...hopefully that will do the trick

    ill have no doubt that the sx can burp with upper 2000watts, 2600+ to be precise. but on the pioneer, maybe 2000watts is good. thought im sure pioneer would do best.

    You've got to build a box with a Qtc of .707, play test tones, from 30-60Hz. Every frequency in that range needs to be played and needs to be metered and recorded. You will notice a certain frequency with a significant increase in decibels compared to the other frequencies. After you have found the golden frequency, you may build a box tuned to that frequency.
