Car Stereos: active crossover layout, rockford fosgate, passive crossovers

Question
Here is what I have.

Head Unit is a Pioneer avhp 5100
Front Components 6.5 JBL 660 GTi with passive crossovers in kick panel pods aimed at me.
Rear Boston Acoustic sl 95  6 x 9 3 ways
Rear Mid Ranges (4) 6.5 Alpine spf 17 pro's 100 rms each with passive crossovers, running a set of each in parallel currently but can change it to series.
12" Alpine swx-1243 3000w dual 4 ohm subwoofer
1 Rockford Fosgate T1500-1bd mono amp  1500w
1 Rockford Fosgate T-600-4 channel
1 Rockford Fosgate T-400-2 channel
AudioControl 6XS Crossover

My Question is this...how would you hook this up?  I have built 2 boxes for my 98 chevy silverado each containing 2 of the alpine spf-17 pros 6.5 woofers (run in parallel) and 1 of the 6 x 9 boston acoustics left and right rear respectively.    

I am not sure if I need another amp...or should I just run the 6 x 9's off the head unit without mixing them into the crossover network and amps especially since they are 3 way and only 60 rms.

Keep in mind my crossover network is 8 channel  Sub, RHP, FHP and RLP.

Your help is greatly appreciated.

Hi David,

The first thing to mention is that your HU can only reasonably put out somewhere in the range of 16w RMS per channel.  So I wouldn't be using the deck to power anything except maybe 3.5" or smaller speakers.

Obviously, your monoblock amp is going to take up the 12" sub.

I'd use the 4 channel to power the 4 6.5" speakers.

I'd use the 2 channel to run the 6x9s

I'd get another amp to power the other set of 6.5"s.  Either that or replace the 2 channel with a 4 channel entirely.
