or could i do better with a single re sx, pioneer spl 3002, or re xxx

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 should find the cabin gain of your vehicle before making any competition boxes.

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.
