It's kind of academic in my case. Though initially I had planned to use 4 channel out from the CS to the JL XD600/6, I decided the best way to go is probably just to use the front two channels (corrected by the CS) and use the 2 ch operation mode of the XD600/6. From what I can gather in the manual, this just duplicates the signal to the second and third set of internal amps, each with independent gain and x-over. So, though I lose my Fade control at the HU, I can effect the similar (static) results with differential gain settings.
