Help getting Alpine head to Alpine EQ

Hi y'all.  I was on this back in it's old Yahoo days, and found answers to everything I ever asked.  Let's hope that still happens.

I am putting a Alpine CDA 7845 unit in my dodge caravan, and want to also use a Alpine EQ (model number 3218) with it.  The problem is that the head has RCA females for Sub, Rear out, and front out. and the eq has one pair RCA (male) input right, and a pair of gray wires marked input right and a pair of white input left..

The eq has out in a pair of RCA females for line out (front)  and a pair of female RCA's for rear.

I am using a power board with two amps and a crossover.

One amp is to run a Atomic 10" sub, and the other to run a pair of ADS plates in the rear door, and a pair of BA 5" pro separates in the dash and door pillar, and another pair of 6" BA pro separates in the front doors.

I think I can handle things once I get out of the eq, but may have to come back for more help.

Thanks for the help.
