hiphop bass

I have been trying to figure this out for the longest and I still have no luck. I'm not looking for a simple sub bass, im looking to make a bass that has that WARMTH, thickness and character to it that gives u that >.< face. I'll post examples. PLEASE HELP.

Freddie joachim is a good example, same with j dilla and 9th wonder
somehow i know it is alot easier to get this sound that im making it out to be. Someone please point me in the right direction tho.
