JD - be careful how much you play with the internal guts and wiring. I have been advised that even changing from a slide-on spade connector at a driver to straight soldering could change the impedance characteristics of that driver, and therefore alter the way the crossover was intended to work by shifting what it passes either up or down or widening it range too much.
Disclaimer - the above statement may make it sound like I know what I am talking about, but I assure you that I do not. I am just regurgitating what a very reliable source had told me.
Perhaps Sean could elaborate with more credibility.
