That is DB's answer to everything. ... and he's right. IF something's not loud enough, turn everything else down.

The problems I have matching loops to kicks is usually phase cancellation like you get when you're mixing techno on decks. Best thing to do if that's your problem is to joins the loops and kicks in a sample as one. I'm sure folks would disagree of you wanna loop sidechaining tricks but there's ways around that too.
