Mike this is the key to a bigger better squat. This is how I learned to do it: I make a focused effort to flex (arch) my lower back hard. Once this is done you simply have to push your ass back, not down, and let biomechanics take over. The tension in your hamstrings is what allows you to balance on the way down and stabilize.
My advice is to work with that pipe at the just below parallel box. You should try to flex your back and hams like I talked about and then make an effort to SLOWLY decend until you barely touch the box.
1 more thing the problem most have when they first start squatting like this is that when they start to get deeper they do not lean forward enough (with low back still arched hard) to keep from falling backward...think about it
