you have to understand that obtaining a good mix is all about balance.
You can have the best sounding kick in the world but if you crowd the space with muddy sub basses and leave it to low in a mix then the kick isn't going to work. Everything in a mix is about balance and finding room for your elements. Similarly if you have a great bass sound then clutter it with other melodic synths and FX. Its all about balance.
an analogy you can use is Think of it like an artist painting a landscape, you gotta find the space and see what works. what important elements need to be in the foreground, what needs to shape your background. You need contrast...you need quiet sounds, you need loud sounds, You need dynamics within your track. How everything works together is ultimately what shapes the outcome of your mix.
So if by 'more power' you mean how to make your track have punch and hit hard in a club then you need to get a good relationship between kick and bass. I mean, to me that is what essentially creates 'the power' in a dance track right? the bass, the low non-directional frequencies that you 'Feel' rather than hear. So if that is what you mean then the first thing I suggest you start with is a good kick and bass relationship.
'A good kick sit in a mix' ......again its all about space and balance. You need room for the kick to breathe, you may want some top end information to help your kick cut through the mix. like I said earlier you can have the best kick in the world but if you clutter that sample by adding too much to the track....that once perfect kick will sink into the mix.
remember 90% of mixing is all about level / volume balance. Focus first on the relationship in volume between all your sounds then dive into your advanced mixing techniques like compression etc.
