Hi thermit,
to get that rolling sound you might try duplicating your kick stem,
then trim a tiny bit off the start of each kick sample, just to take away some of the punch.
Then add reverb to it till you get a bassy rumble with a tail that decays before the nxt kick is triggered.
Then eq the top end off so it's all low. also a little saturation might work
you can move the copied kicks/bass around in the mix if it sounds any better.

There is a half decent tutorial on YouTube on this. I will try find it for you :)
