With my 2 12's it was too loud to hear any rattle at full tilt. At about 1/2, everything rattled. The most annoying thing was my OHC, which at the time I wish I never installed. But just lay down at least 3 layers of dynamat or equivalent everywhere and you'll be fine.
I got mine to the point where w/o dynamat I was making the cab almost touch the bed...but it's not very hard to do that in a truck.
