Thanks, I just hope spending all this time and money will pan out and I will get an empeg!
Here are the specs for my 6x9s:
6x9 midrange/bass cone
1" tweeter (all titanium if I remember)
4ohm
30hz-21khz freq response
125watts peak 90watts continuous
92dB 1w/1m

However, (hear cash registers ringing)
I have been eyeing the MB Quart 6x9s. My local shop has them for $199 2way or $249 3way.

I checked the manual and if I use the line out on the first amp (4200 running 4ohm 4way) it makes it a 90hz lowpass output to the second amp (2200 bridged 4ohm mono). That is why I was wondering if I might need a crossover if I want to run the sub with a little higher frequency range. Else I would loose the front/rear fade-ability if I took the rear set of preouts off of the 4200 and put them on the 2200.

Believe me, you will probably be able to see my grin on this board when I get all of this working!

again I welcome all input...
