It might be eq man. I try not to rely on side chaining.
It could be volume staging and eq. For a long time i fought with getting the bass and kick to sit right. In my mixes i tend to have the drum group the loudest in relation to every thing else (very little group volume augmentation) and leave the sub to go straight into your master or premaster channel/group.
I adjust the sub bass to not over power, but if you're cutting your frequencies in your kick to just let the sub carry most of the sub sonic weight, then you're in for a good deal.
I'd also try to make the sub sit a little lower than the kick drum. This last advice is a little tricky, because you'd need to use your feeling and ears rather than your eyes, because if you would drop your sub that low, it might not even exist.
I'd also advise you maybe layer in a more audible bass frequency that plays the sub part, just so it's more in the bass than the sub sonic region.
I listened to your track as well, it sounds alright, but the top end isn't pleasant to listen to. The overall perspective is kinda thin.
The bass is loud and clear, but compared to, currently listening to truth's mix
TRUTH CHRONICLES, i can hear your sub clearly at a low volume on consumers, where his is more attenuated towards the drums and music.
It could be a perspective you carry in the mix that is affecting the way you're treating the bass. Out side of every advice posted, that's just my two cents.
