No problem, I really like doing this sort of stuff. Take note of the wires and which goes to which driver (there are two per driver and the polarity is important, so perhaps mark the wires A-D and also mark the crossover boards the same letter) Its possible that one wire from the drivers might connect directly to the binding posts as well, and also there could be more than one board in there. Also note how much larger you think the boards can be and still fit, as most likely we will want to make things a bit bigger usually the woofer hole is one of the limiting factors in the size, as you'd likely suspect.
