does the ported box have anything to do with the bottoming out of the subs????? Ive always been pretty biased towards ported boxes....

Bottoming out is simply the overexcusion of a sub, causing the voice coil former to hit the back plate of the motor. It can happen in any box, but is most common in ported boxes when the sub is playing too far below tuning and acts as though it isn't in a box at all, causing it to overexcurt easily. Tune low enough and you really don't have to worry about it.

is your box a prefab, or is it built to specs for the sub?

box is prefabricated...its basically designed to the limited space in these 07^ single cab gms than to the recommendations for the sub...

Also, bottoming out only happens if the motor is the limiting factor of the cone's movement, aka: a motor limited design. The other is suspensions limited, which will result is damaged soft parts(surround and spiders are most common) when excursion reaches a certain point.

its very easy to bottom out a motor limited sub in a prefab box,

they often times end up being too big or tuned too high to let the sub play properly on a large range of music,

Have you gotten the problem fixed yet man?

bottom line is run your amp @ 2 ohm with those subs and you may see alot of these nuances go away... provided you set the amp up right and dont wind on it since you are probably able to be conservative on the knobs @ 1/2 ohm and dont have to turn it up too far

x10 on the wiring to 2 ohm. If the amp isnt stable at .5 ohm you will be having problems as stated. If you want it to be louder than it is at 2 ohms then get a different amp or setup.
