Off the top of my head, I'd suggest using a parametric EQ (or plug-in) and sweep the kick (and bass) by hand until you find a combination that delivers the kind of sonic power you're looking for. But don't be fooled into being afraid to roll off the very bottom of both. Too much subsonics will suck up all the power in the mix and leave it competitively unloud... roll out the very lowest (maybe starting in the 35-40-45 Hz range and dropping pretty steeply from there so that there's virtually nothing below 20 Hz). (You may want to use a multi-band eq so that you can boost and cut in various ranges.)
That will have the ancillary benefit of tightening up and helping to define both bass instruments. But if you don't roll much above 35-45 you'll still have plenty of meat in your beat (sorry).
You'll probably do yourself a favor (as others have suggested) by scooping a little out of the bass to make room for the kick. The range above 125-150 Hz helps give bass tone and warmth so you can often roll the very lowest bass off a bit (maybe under 90-100 Hz... but it really depends on the key of the track where and how much you want to cut. And, in fact, you might want to scoop the bass, rather than roll it off, depending on what you're doing and the style of music. Sometimes you really do want the bass voice to shake the walls. Just watch out for those pesky subsonics (so, actually, I guess we might be talking about scooping and then rolling... sounds sort of like baking.)
