Help pick out final comp. for my system rebuild

I need some help on recommendations on a new eq/xover/sound processor. This is what I have so far:

Interior speakers: 6X Polk MMC650's
Interior amp: PDX-4.150
Tower speakers: 2X Handmade 8" coaxial speakers (500W RMS each)
Tower amp: PDX-4.150
Sub: S15L74 in sealed box under drivers console
Sub amp: PDX-1.1000
HU: Stock clarion XMD-1 (dont want to change it because I like the remote)

My amps should be here tomorrow. I will pick up the sub at a local dealer here. I still have to make the enclosure. I still have to redo the temporary wiring board. I like the design that I have but I need to use some composite of some sorts.

Here are my wishes in a do all eq/xover/processor:

1) Fader control of either the sub or the tower amp (preferably the tower amp)
2) Indepent Xover for the three amps
2) EQ with enough adjustability for to fine tune all sets of speakers independently for the flattest response. I have a pretty good old school SPL meter that I can use for RTA to get the best settings.
3) Aux in. Would be a nice to have. I already have the aux in for the CD player.
4) Full DSP. I'm really into gadgets and getting on the cutting edge of stuff. Since we are going pretty all out (relatively speaking, sorry no arc audio or zapco amps), I'd like to not skimp on this component. It would be nice to have something with some sort of PC interface that has the ability to graphically see what is going on. I like the eyecandy stuff. Eventhough it is usually a set once type of thing, it's still fun to tinker around with that stuff.

I have been researching a few options. I wanted to know if any of you all have any experience or feedback on the following devices:

DSP6-S: Pretty cool stuff, but way over budget

Rockford 3Sixty.2: Mainly for OEM, but has some pretty good features that might be good for what I want. I have been reading a bunch of forums where people have used this in full aftermarket systems with some pretty good success.

Audiocontrol DQXS
Alpine PXE-H650: Haven't figured out if this has RCA level inputs yet

I'm all about using technology that allows you to press the easy button to get you close, and then has enough flexibility to make up for the inaccuracies in it's calculation.

Hopefully in the end, I will end up with a pretty nice sounding and stable system.



Cheers!
