Different horses for courses mate.

It all deppens on your kick, and you bass. There is no golden rule to this, and its all about learning by ear how it should sound. I use different compressors and maximisers for different effects on the kick and bass. I generally use the fruity compressor to round my kick off, then sidechain the bass to the output of the compressed kick to give it more of a pump. Then i'l compress them together with a suitable compressor for the job. If you look at your compressor values, and know what they do, then you can have a better idea on how to shape the dynamics to taste.

Threshold - At what level the compressor starts working at. (if you want the whloe of the kick to sound squashed, turn this right up)

Ratio - The level of compression when the threshold is hit.

Attack - How soon the comressor starts working, (if you want a snap at the beggining, 15ms will give this, if you want to round the kick off, put this a lot lower)

Release - How soon the compressor stops working after the threshold limit has past. (If you want to attenuate a hard roll of on the kick, then leave this quite high. If your roll off is quite quiet, then shorten the release.)
