That booklet does contain an impressive amount of info, though I can't help but notice the oh-so-StewMac list of 18 required and suggested tools they can sell you. But even this subsection of their layout is like one of those "What's wrong with this drawing?" puzzles. Even if the novice builder sees the subtle gray wire linking the lugs on the tag strips, I see five or six things that aren't right, or at least aren't best practice, and that's before you count the wire colors, which sorta scream "built by noob." The amp would work wired this way. That's about all I can say on the plus side. For the benefit of the OP, Rob's layout is better in all regards.
