All of my kicks are created using this method:
1. Before getting started, it's important to note that I route my kicks directly to the kick group, and then straight to the master, and all of the rest of the percussion elements, claps, snares, hats, and all that is routed directly to a sum drum bus where they're compressed/EQ'd.
2. I usually group roughly two/three different samples I wanna use for my kick. Low/sub frequency, mid frequency, and high/click.
3. After finding the samples I like most, I'll EQ each sample to taste, and mix each sample in. The kick mix is referenced both solo, and with the track as a whole.
4. Lightly compress the kick group to glue everything together.
Kinda hard to explain right now, but if anyone wants any other information, more than happy to help.
