I finally have everything either in my possession or out on a truck somewhere heading my way. I want to thank everyone here that took time to answer my questions.

Head unit - Kenwood DDX372BT

Sound processor - JBL MS-8 dsp

Amps - PPI P1000.1, PPI P600.2, PPI P900.4

Subs - (3) JL Audio 12w3v3 - 4 ohm

Highs - PPI P65c3

The P1000.1 will power the three subs in a sealed enclosure. The components will be run active with the P600.2 running the 6.5's in the factory door locations, two channels of the P900.4 running the 3's in the factory dash locations and the other two channels of the P900.4 powering the tweeters in the a-pillars.

I will say the MS-8 really comes alive using rear fill. Tuning it with and without, with is ten fold better. So much fuller and more detailed stage.

Its still good without but you are missing out big time

If it had one more channel I would love to do rear fill.

It's worth only doing a 2 way front

I guess I can use the MS-8 differently than I had planned.

Outputs 1/2 - 6 1/2 fronts

Outputs 3/4 - 3" and tweeters using the amp crossover

Outputs 5/6 - rear fill off of the MS-8 amp

Outupt 7 - sub

I placed the order for a pair of PPI P.652 components for rear fill last night. Thanks for the advice.
