Here you go, started working on this two days ago and i literally did nothing but working on the low end and, as you can hear, it's so far from being ok https://soundcloud.com/mohanad303/untitled-1/s-pB3wo

your kick tail is extremely long.

shorten it to 1/4 of a bar.

have your sub sidechain to 3/4 of a bar - lfotool or kickstart will take care of that.

your sub energy right now is like offbeat melbourne bass - kick taking up half the bar and sub on the other.

remove any pitch envelope you might have on the sub. make it flat with sloped attack/release to get rid of clicks.

highcut your rolling bass at 100hz with a 72db/oct slope. good sub energy doesn't get past 100.

here's the routing part:

bass(highpassed) routed into the sub channel.

compress the channel with a glue compressor 3-4dbs off.

route the bass/sub channel to the kick.

throw in a simple limiter - MLimiter from melda is good. use the clip 3 shape. check a visualizer- the kick and bass/sub channel should be hitting the same ceiling.
