DSP Wiring Question

[Leberbs]

I have a 2022 Dodge 1500 Big Horn Crew Cab that I'm planning a system for.

 

I have the 6Channel PAC device (Front, Rear, and Sub) and a 5Channel amp (Front, Rear, and Sub). That's the base plan.

 

I also have a 2 channel amp and an Alpine Optim6.

 

This truck trim has 2 dash speakers, 2 front speakers, and 2 rear speakers.

My questions are...

 

1. Can I put 2 RCA Y-spliters on the front channels of the PAC?
2. Can I take those 4 RCAs into inputs 1-4 of the Optim6?
3. Out of the Optim6 into the front and rear channels of my 5channel amp to control/tune my component speakers independently?
4. Out of PAC rear RCAs to Optim6 inputs 5-6?
5. Into the 2channel amp to power the rear speakers?
6. Out of the PAC sub RCAs into the sub input of the 5channel amp and set the crossover at the amp level?
7. Control all other EQ functions via the Optim6?

 

Is this the correct way to go about wiring everything up?

 

Thanks in advance!
